These long working distance lenses may cost more, but they can be worth it. If you accidentally scratch or break a regular lens, you have to replace it, which can be expensive. But with these special lenses, you might not need to replace them as often. So, even though they cost more upfront, they could save you money in the long run.I’m planning to buy a set of long working distance lenses myself. They offer an optical upgrade and the extra benefit of being able to focus on things that are farther away. It seems like a good investment for better microscope observations.Objective TypeMagnificationWorking Distance (mm)Achromatic4X37.4Achromatic10X6.6Achromatic40X0.64Achromatic100X (Oil)0.19LWD Plan Achromatic4X11.98LWD Plan Achromatic10X11LWD Plan Achromatic40X2.9LWD Plan Achromatic100X (Oil)0.12Shortest Working Distance Objective LensThe shortest working distance objective lens is the 100X objective lens. This lens is often used with oil to achieve a specific level of clarity. When you use this lens, you need to get very close to the glass slide, but you have to be careful not to touch it.To make the image really clear, the 100X lens usually needs to be put in oil. This oil helps the lens capture more details. It’s like putting on glasses to see things better. But you need to be really close to the slide, and the lens tip goes into the oil without touching the slide.Now, there are also 100X lenses that you can use without oil. These lenses have a short working distance too. Take the example of a 100X dry objective from LW Scientific. This lens doesn’t need oil, but it can still see things really clearly. It’s a bit different from the usual oil immersion lens, and it gives you more space between the lens and the slide. This is helpful because you won’t have to worry about the lens touching the slide while still getting a good view.Working distance in the work place – real life examples.In the workplace, working distance plays a significant role when dealing with tasks, tools, and materials. It becomes especially important when you’re handling objects that have different heights or sizes. Being able to see both distant and nearby details can be crucial.Let’s take a look at a few real-life examples:Soldering: When you’re soldering, you need to ensure a safe working environment. This involves having a fume extractor nearby to remove any harmful fumes. You not only need space for your soldering tools like the soldering iron and solder, but also for the fume extractor. Proper working distance helps in arranging these items effectively.Handling Small Samples: Sometimes, you might work with tiny items that are closely packed together. To manipulate these items using tools like tweezers, probes, or pipettes, you need to approach them at the right angle. If the working distance is too short, it might be difficult to access these samples and perform delicate tasks.Variations in Sample Height: Certain materials or samples can have varying heights. In such cases, you need to focus on both the farthest and nearest details. Having a sufficient working distance allows you to adjust your focus to observe the different parts of the sample effectively.In all these situations, the proper working distance ensures that you can work efficiently and safely. It provides the necessary space to accommodate tools, equipment, and variations in the objects you’re working with. This ability to maintain the right distance can greatly enhance the quality and precision of your work.Relationship Between Magnification and Working DistanceThe connection between magnification and working distance is quite interesting. It’s like a seesaw – when one goes up, the other goes down.When you’re using lower magnification, you can keep the lens a bit far from the object you’re looking at. This is called a long working distance. But as you want to zoom in more and make things bigger, you have to move the lens closer to the object. This makes the working distance much shorter.For example, if you’re using really powerful lenses, like the 100x ones, they need to be very, very close to the object. They’re so close that sometimes they need oil to help them see better. But being this close can be tricky – you might accidentally touch and damage the object you’re studying. It’s like getting super close to something delicate. So, it’s important to be careful when using these lenses.Remember, it’s a trade-off: the more you magnify, the closer you need to be to the object. So, when you’re using a microscope, you’re not just looking at tiny things – you’re also figuring out how to balance magnification and distance to see things clearly and without causing any harm. It’s a neat lesson in science and patience!FAQWhat is working distance in a microscope?Working distance in a microscope is the space between the objective lens and the object you’re observing. It’s important because it affects how close you need to be to the object to see it clearly.How does working distance relate to magnification?Working distance and magnification are inversely related. As you increase magnification, you need to move the lens closer to the object for a clear view.Why do some objective lenses require oil immersion for optimal working distance?Oil-immersion lenses, like the 100x objective, need oil between the lens and the slide to achieve maximum clarity. The oil helps capture more details and improve the image quality.Why is longer working distance preferred for some observations?Longer working distance is preferred when observing specimens that are not flat or emit harmful substances. It provides more space and reduces the risk of damaging the object or the lens.What happens if the working distance is too short?A short working distance can make it challenging to manipulate tools and might lead to accidental contact between the lens and the specimen, potentially causing damage.How is working distance measured and indicated on an objective lens?Working distance is usually indicated on the objective lens barrel using the letters “WD,” followed by the distance in millimeters (e.g., “WD: 0.5” or “0.5 EL WD”).Can working distance affect the cost of a microscope lens?Yes, lenses with longer working distances might cost more due to their specialized design and ability to reduce the risk of damage, potentially saving money in the long run.Are there alternatives to oil immersion lenses for achieving short working distances?Yes, some dry objective lenses can provide short working distances without the need for oil immersion, but they may have slightly different characteristics.Why is it important to balance working distance and magnification?Balancing working distance and magnification ensures clear and accurate observations without damaging the specimen or the lens. It’s about finding the right distance for the best results.Can you measure working distance using a digital caliper?While it’s possible to measure working distance using a digital caliper, it’s not recommended as it could potentially damage the lens or compromise your microscope’s performance. It’s safer to rely on manufacturer specifications or inscriptions on the lens barrel.Referenceshttps://www.visioneng.us/resources/articles/working-distance-a-simple-explanation/https://opticsmag.com/what-is-working-distance-in-a-microscope/https://microscopeclarity.com/what-is-working-distance/https://www.e-education.psu.edu/mcl-optpro/theory/node801https://www.olympus-ims.com/en/microscope/terms/working_distance/https://www.rp-photonics.com/working_distance.htmlhttps://blog.microscopeworld.com/2014/08/microscope-working-distance.htmlhttps://www.celestron.com/blogs/knowledgebase/what-is-the-working-distance-of-my-microscopehttps://pages.mtu.edu/~shene/DigiCam/User-Guide/Close-Up/BASICS/Working-Dist.htmlhttps://www.vision-doctor.com/en/optical-calculations/calculation-working-distance.htmlhttps://sciencing.com/difference-between-compound-dissecting-microscopes-5576645.htmlhttps://www.meetoptics.com/academy/working-distancehttps://www.newport.com/f/long-working-distance-objectives

Exposure to a stable and regular daily  light-dark cycle has the following beneficial effects on the human body and brain:

The microscope has two main types of working distances:Objective Working Distance: This is the space between the closest part of the object you’re looking at and the front lens of the objective. It’s like the gap you have to work with when you put the object under the lens and make it clear to see. Sometimes, the measurement includes the cover on top of the slide.Stage Working Distance: This is the space you can see clearly when you move the tube, arm, or stage of the microscope up and down. When you add this to the objective working distance, it decides how thick or big an object can be while you can still see it properly. If you need to look at larger objects, it’s better to use a long working distance.Both of these working distances help you observe things under the microscope and make sure they’re in focus. They define the space you have to work with and how big the object can be while still staying clear to see.How Does It Work?Understanding how a microscope works is important, especially when observing different things. The right distance between the microscope and the object you’re looking at is crucial. Some objects might be harmful or not flat, so you need to adjust the lens to be farther away.The working distance of a microscope can be really helpful when you need more space between the microscope and the object. Usually, if you zoom in a lot (make things look bigger), the working distance becomes shorter. But when you increase the zoom, the working distance gets smaller.To change the working distance, you have to use different lenses. These lenses go on the part of the microscope that’s looking at the object. They can either make things look bigger or smaller and also change how far the microscope needs to be.If you put on a lens that makes things look bigger, the object gets magnified, but you need to get closer to it. And if you put on a lens that makes things look smaller, the object gets smaller, but you can be farther away from it.The working distance can be as long as 50 millimeters (that’s like the length of your thumb) or as short as 0.1 millimeters (that’s really tiny). As you make things look clearer, bigger, and zoom in more, the working distance gets tinier.Objective Working and Parfocal Distance | Image Source: https://www.microscopyu.com/microscopy-basics/working-distance-and-parfocal-lengthHow to Find the Working Distance for an Objective LensTo determine the working distance of an objective lens, you have a few methods to consider. Here’s how you can do it:Check the Inscription: Look at the objective lens barrel for an inscription. It might have the letters “WD,” which stands for “working distance,” followed by a measurement in millimeters. For example, you might see “WD: 0.5” or “0.5 EL WD.” This indicates that the working distance is 0.5 millimeters. When your focus is sharp while using this objective, it means the lens is positioned 0.5 millimeters away from the slide coverslip.Manufacturer Specifications: Another way is to refer to the manufacturer’s specifications. These details are usually provided with the objective lens or can be found on the manufacturer’s website. Look for a section that outlines the working distance for each specific objective lens.Digital Caliper (Cautionary Method): If you can’t find the working distance using the previous methods, there’s a third option, but it requires caution. You could use a digital caliper to carefully measure the distance to the objective lens. However, this method is not recommended as it might harm or smudge the nearby lenses. It’s best to avoid this method unless you’re absolutely sure and willing to take the risk.How to Find the Working Distance for an Objective Lens | Image Source: https://blog.microscopeworld.com/2014/08/microscope-working-distance.htmlBy following these steps, you can find out the working distance of an objective lens accurately and safely. Always prioritize the methods that offer the least risk of damage or disruption to your microscope equipment.Why is Working Distance Important?The concept of working distance is very important. Imagine you’re trying to look at something under a microscope, like a tiny object that isn’t completely flat or releases harmful substances. Would you prefer the microscope lens to be really close or a bit far from that object? Of course, you’d want the lens to be farther away. Having more distance between the lens and the object can be very useful when you’re studying things that need space.Now, let’s talk about powerful microscope lenses. These lenses need to be closer to the light and the object because they have a special quality called “numerical aperture.” When experts make lenses that give you more space to work with (long working distance), they have to make sure they still fix any issues with the lens to make the image clear.Using lenses with longer working distances can also help protect your microscope’s powerful lenses from harm. When lenses are farther away, they are less likely to get damaged. Even though you can be careful when focusing, sometimes accidents happen, and you might bump the lens against the glass slide.So, working distance matters a lot because it helps you observe objects properly, especially when they’re not flat or might be risky to get too close to. It also affects the type of lenses you use and how they’re designed to work best.Long Working Distance Objective LensesLong working distance objective lenses are a special kind of lenses used in microscopes. They are made to focus on things that are farther away compared to regular lenses. These lenses are designed to fix any issues that might happen because of the longer distance.Let’s look at a comparison of working distances between regular lenses and long working distance lenses:Regular Achromatic Lenses:4X magnification: 37.4 mm working distance10X magnification: 6.6 mm working distance40X magnification: 0.64 mm working distance100X magnification (Oil): 0.19 mm working distanceLong Working Distance (LWD) Plan Achromatic Lenses:4X magnification: 11.98 mm working distance10X magnification: 11 mm working distance40X magnification: 2.9 mm working distance100X magnification (Oil): 0.12 mm working distanceThese long working distance lenses may cost more, but they can be worth it. If you accidentally scratch or break a regular lens, you have to replace it, which can be expensive. But with these special lenses, you might not need to replace them as often. So, even though they cost more upfront, they could save you money in the long run.I’m planning to buy a set of long working distance lenses myself.

For people 45-50 years and older, higher light intensities and probably spectral changes may be needed to support visual and non-visual (biological and emotional) needs. This is largely due to the normal degrading processes that happen in the eye. Many people recognize this as the time when they start needing reading glasses.

Working distance in a microscope is the space between the objective lens and the object you’re observing. It’s important because it affects how close you need to be to the object to see it clearly.

Use a lighting system that enables you to change the light level; dimming =reducing the light level and/or boosting =increasing the light level.

The amount of daylight we are exposed to outdoors varies during the day both because daylight itself is ever changing and because we are moving around ourselves, changing what we look at and see, and making changes to the space we are in like sitting in the shade. It might be advantageous to mimic these changes to some extent indoors. People need high light levels during the day, and low light levels during the evening before going to sleep. Good Light indoors is stimulating during daytime with an intensity that preferably exceeds the traditional standards for indoor lighting by a factor 5, while during the evening the preferable light level is dimmed by a factor 5, provided it remains comfortable and safe.

I’m planning to buy a set of long working distance lenses myself. They offer an optical upgrade and the extra benefit of being able to focus on things that are farther away. It seems like a good investment for better microscope observations.Objective TypeMagnificationWorking Distance (mm)Achromatic4X37.4Achromatic10X6.6Achromatic40X0.64Achromatic100X (Oil)0.19LWD Plan Achromatic4X11.98LWD Plan Achromatic10X11LWD Plan Achromatic40X2.9LWD Plan Achromatic100X (Oil)0.12Shortest Working Distance Objective LensThe shortest working distance objective lens is the 100X objective lens. This lens is often used with oil to achieve a specific level of clarity. When you use this lens, you need to get very close to the glass slide, but you have to be careful not to touch it.To make the image really clear, the 100X lens usually needs to be put in oil. This oil helps the lens capture more details. It’s like putting on glasses to see things better. But you need to be really close to the slide, and the lens tip goes into the oil without touching the slide.Now, there are also 100X lenses that you can use without oil. These lenses have a short working distance too. Take the example of a 100X dry objective from LW Scientific. This lens doesn’t need oil, but it can still see things really clearly. It’s a bit different from the usual oil immersion lens, and it gives you more space between the lens and the slide. This is helpful because you won’t have to worry about the lens touching the slide while still getting a good view.Working distance in the work place – real life examples.In the workplace, working distance plays a significant role when dealing with tasks, tools, and materials. It becomes especially important when you’re handling objects that have different heights or sizes. Being able to see both distant and nearby details can be crucial.Let’s take a look at a few real-life examples:Soldering: When you’re soldering, you need to ensure a safe working environment. This involves having a fume extractor nearby to remove any harmful fumes. You not only need space for your soldering tools like the soldering iron and solder, but also for the fume extractor. Proper working distance helps in arranging these items effectively.Handling Small Samples: Sometimes, you might work with tiny items that are closely packed together. To manipulate these items using tools like tweezers, probes, or pipettes, you need to approach them at the right angle. If the working distance is too short, it might be difficult to access these samples and perform delicate tasks.Variations in Sample Height: Certain materials or samples can have varying heights. In such cases, you need to focus on both the farthest and nearest details. Having a sufficient working distance allows you to adjust your focus to observe the different parts of the sample effectively.In all these situations, the proper working distance ensures that you can work efficiently and safely. It provides the necessary space to accommodate tools, equipment, and variations in the objects you’re working with. This ability to maintain the right distance can greatly enhance the quality and precision of your work.Relationship Between Magnification and Working DistanceThe connection between magnification and working distance is quite interesting. It’s like a seesaw – when one goes up, the other goes down.When you’re using lower magnification, you can keep the lens a bit far from the object you’re looking at. This is called a long working distance. But as you want to zoom in more and make things bigger, you have to move the lens closer to the object. This makes the working distance much shorter.For example, if you’re using really powerful lenses, like the 100x ones, they need to be very, very close to the object. They’re so close that sometimes they need oil to help them see better. But being this close can be tricky – you might accidentally touch and damage the object you’re studying. It’s like getting super close to something delicate. So, it’s important to be careful when using these lenses.Remember, it’s a trade-off: the more you magnify, the closer you need to be to the object. So, when you’re using a microscope, you’re not just looking at tiny things – you’re also figuring out how to balance magnification and distance to see things clearly and without causing any harm.

Consider using more advanced lighting systems which include environmental sensors beyond those applied to measure and control the lights. Incorporating sensors like temperature, noise detection, air quality can serve to safeguard and support health and wellbeing of the users. These types of Indoor Environmental Quality sensors should be connected to other building automation systems.

In the next table you will find our recommendations for horizontal light levels. These levels are based on the current knowledge, and a combination of best practices and scientific arguments. Please note that these light levels must remain comfortable and adequate for the age of the user and the specific task. The horizontal intensity criterion also depends on the spectrum (see following paragraph), lighting design, and environment. Timing should be personalised so that it supports personal schedules.

Working distance and magnification are inversely related. As you increase magnification, you need to move the lens closer to the object for a clear view.

Good light is the right light at the right time tailored to our activities and personal needs, every day of our life. Good light is natural light, or electric lighting indoors that mimics the beneficial properties of natural light as much as possible. The wrong light at the wrong time may result in problems such as mood disturbances, sleep problems, difficulties with learning and memory, problems with vision in the short term, and health problems in the long term.

Provide horizontal and vertical light levels that ensure adequate visual performance and comfort, while simultaneously providing non-visual (biological and emotional) benefits.

The recommended levels in the table below are partly based on recent recommendations of a group of scientists, and age corrections, and partly based on our own interpretation thereof.

Design not only for horizontal light levels as suggested in most lighting application standards, but also for light on the eye. During most daytime activities, this is the vertical light level at sitting or standing height.

Increase the overall brightness of the room, don’t only light the work surface or task but light the surroundings e.g. the walls and the ceiling.

*Melanopic equivalent daylight illuminance (in the table abbreviated to MEDI) is one of the metrics defined in the international Standard CIE S026:218 recommended to be used in measuring the non-visual effects of light

Many individual users appreciate having personal control over the dynamics and spectral characteristics of the light. The amount of control, or adaption ranges can be selected by the system and made time of day dependent.

So, working distance matters a lot because it helps you observe objects properly, especially when they’re not flat or might be risky to get too close to. It also affects the type of lenses you use and how they’re designed to work best.

Balancing working distance and magnification ensures clear and accurate observations without damaging the specimen or the lens. It’s about finding the right distance for the best results.

Just like in nature, indoor light should be attractive, comfortable and of high quality. This is achieved when indoor lighting shows colours naturally, does not cause too much glare, does not have unwanted artifacts or flicker, provides attractive contrast, lights the space comfortably, does not make noise and feels safe.

Just like in nature, the spectral properties (colours) of ideal indoor light vary as a function of the time of day. Light spectrum can be optimized to meet personal needs and preferences and to support specific tasks. During the day, the light spectrum should include a reasonable portion of short wavelengths (cyan light colour) to provide the energizing and revitalizing benefits of light. In the evening and at night, the amount of short wavelengths should be minimized to support winding down, enabling a good night’s sleep and preventing disruption of the day-night rhythm. With age, from 45-50 years and older, the spectral characteristics required for optimal functioning may change because of changes in the eye, e.g. in the case of the development of cataracts.

Working distance is usually indicated on the objective lens barrel using the letters “WD,” followed by the distance in millimeters (e.g., “WD: 0.5” or “0.5 EL WD”).

Both of these working distances help you observe things under the microscope and make sure they’re in focus. They define the space you have to work with and how big the object can be while still staying clear to see.How Does It Work?Understanding how a microscope works is important, especially when observing different things. The right distance between the microscope and the object you’re looking at is crucial. Some objects might be harmful or not flat, so you need to adjust the lens to be farther away.The working distance of a microscope can be really helpful when you need more space between the microscope and the object. Usually, if you zoom in a lot (make things look bigger), the working distance becomes shorter. But when you increase the zoom, the working distance gets smaller.To change the working distance, you have to use different lenses. These lenses go on the part of the microscope that’s looking at the object. They can either make things look bigger or smaller and also change how far the microscope needs to be.If you put on a lens that makes things look bigger, the object gets magnified, but you need to get closer to it. And if you put on a lens that makes things look smaller, the object gets smaller, but you can be farther away from it.The working distance can be as long as 50 millimeters (that’s like the length of your thumb) or as short as 0.1 millimeters (that’s really tiny). As you make things look clearer, bigger, and zoom in more, the working distance gets tinier.Objective Working and Parfocal Distance | Image Source: https://www.microscopyu.com/microscopy-basics/working-distance-and-parfocal-lengthHow to Find the Working Distance for an Objective LensTo determine the working distance of an objective lens, you have a few methods to consider. Here’s how you can do it:Check the Inscription: Look at the objective lens barrel for an inscription. It might have the letters “WD,” which stands for “working distance,” followed by a measurement in millimeters. For example, you might see “WD: 0.5” or “0.5 EL WD.” This indicates that the working distance is 0.5 millimeters. When your focus is sharp while using this objective, it means the lens is positioned 0.5 millimeters away from the slide coverslip.Manufacturer Specifications: Another way is to refer to the manufacturer’s specifications. These details are usually provided with the objective lens or can be found on the manufacturer’s website. Look for a section that outlines the working distance for each specific objective lens.Digital Caliper (Cautionary Method): If you can’t find the working distance using the previous methods, there’s a third option, but it requires caution. You could use a digital caliper to carefully measure the distance to the objective lens. However, this method is not recommended as it might harm or smudge the nearby lenses. It’s best to avoid this method unless you’re absolutely sure and willing to take the risk.How to Find the Working Distance for an Objective Lens | Image Source: https://blog.microscopeworld.com/2014/08/microscope-working-distance.htmlBy following these steps, you can find out the working distance of an objective lens accurately and safely. Always prioritize the methods that offer the least risk of damage or disruption to your microscope equipment.Why is Working Distance Important?The concept of working distance is very important. Imagine you’re trying to look at something under a microscope, like a tiny object that isn’t completely flat or releases harmful substances. Would you prefer the microscope lens to be really close or a bit far from that object? Of course, you’d want the lens to be farther away. Having more distance between the lens and the object can be very useful when you’re studying things that need space.Now, let’s talk about powerful microscope lenses. These lenses need to be closer to the light and the object because they have a special quality called “numerical aperture.” When experts make lenses that give you more space to work with (long working distance), they have to make sure they still fix any issues with the lens to make the image clear.Using lenses with longer working distances can also help protect your microscope’s powerful lenses from harm. When lenses are farther away, they are less likely to get damaged. Even though you can be careful when focusing, sometimes accidents happen, and you might bump the lens against the glass slide.So, working distance matters a lot because it helps you observe objects properly, especially when they’re not flat or might be risky to get too close to. It also affects the type of lenses you use and how they’re designed to work best.Long Working Distance Objective LensesLong working distance objective lenses are a special kind of lenses used in microscopes. They are made to focus on things that are farther away compared to regular lenses. These lenses are designed to fix any issues that might happen because of the longer distance.Let’s look at a comparison of working distances between regular lenses and long working distance lenses:Regular Achromatic Lenses:4X magnification: 37.4 mm working distance10X magnification: 6.6 mm working distance40X magnification: 0.64 mm working distance100X magnification (Oil): 0.19 mm working distanceLong Working Distance (LWD) Plan Achromatic Lenses:4X magnification: 11.98 mm working distance10X magnification: 11 mm working distance40X magnification: 2.9 mm working distance100X magnification (Oil): 0.12 mm working distanceThese long working distance lenses may cost more, but they can be worth it. If you accidentally scratch or break a regular lens, you have to replace it, which can be expensive. But with these special lenses, you might not need to replace them as often. So, even though they cost more upfront, they could save you money in the long run.I’m planning to buy a set of long working distance lenses myself. They offer an optical upgrade and the extra benefit of being able to focus on things that are farther away.

Avoid Discomfort Glare: design for a Unified Glare Rating (UGR) of 19 or less in longstay areas (≥30 min) and for UGR ≤ 22 in short-stay areas (<30 min).

Studies recommend that for periods longer than 20-30 minutes on sunny and/or warm days, you should protect your skin and eyes in an appropriate way against an overdose of UV radiation from the sun. The most common ways to do this is by wearing protective cloths, a cap, sunglasses, by using sunscreen and/or simply moving to the shadow. Wearing a cap reduces the light coming into your eyes by ~50%, wearing sunglasses reduces the light coming into your eyes by 5-95% depending on the type of glasses.

Yes, some dry objective lenses can provide short working distances without the need for oil immersion, but they may have slightly different characteristics.

Long working distance objective lenses are a special kind of lenses used in microscopes. They are made to focus on things that are farther away compared to regular lenses. These lenses are designed to fix any issues that might happen because of the longer distance.Let’s look at a comparison of working distances between regular lenses and long working distance lenses:Regular Achromatic Lenses:4X magnification: 37.4 mm working distance10X magnification: 6.6 mm working distance40X magnification: 0.64 mm working distance100X magnification (Oil): 0.19 mm working distanceLong Working Distance (LWD) Plan Achromatic Lenses:4X magnification: 11.98 mm working distance10X magnification: 11 mm working distance40X magnification: 2.9 mm working distance100X magnification (Oil): 0.12 mm working distanceThese long working distance lenses may cost more, but they can be worth it. If you accidentally scratch or break a regular lens, you have to replace it, which can be expensive. But with these special lenses, you might not need to replace them as often. So, even though they cost more upfront, they could save you money in the long run.I’m planning to buy a set of long working distance lenses myself. They offer an optical upgrade and the extra benefit of being able to focus on things that are farther away. It seems like a good investment for better microscope observations.Objective TypeMagnificationWorking Distance (mm)Achromatic4X37.4Achromatic10X6.6Achromatic40X0.64Achromatic100X (Oil)0.19LWD Plan Achromatic4X11.98LWD Plan Achromatic10X11LWD Plan Achromatic40X2.9LWD Plan Achromatic100X (Oil)0.12Shortest Working Distance Objective LensThe shortest working distance objective lens is the 100X objective lens. This lens is often used with oil to achieve a specific level of clarity. When you use this lens, you need to get very close to the glass slide, but you have to be careful not to touch it.To make the image really clear, the 100X lens usually needs to be put in oil. This oil helps the lens capture more details. It’s like putting on glasses to see things better. But you need to be really close to the slide, and the lens tip goes into the oil without touching the slide.Now, there are also 100X lenses that you can use without oil. These lenses have a short working distance too. Take the example of a 100X dry objective from LW Scientific. This lens doesn’t need oil, but it can still see things really clearly. It’s a bit different from the usual oil immersion lens, and it gives you more space between the lens and the slide. This is helpful because you won’t have to worry about the lens touching the slide while still getting a good view.Working distance in the work place – real life examples.In the workplace, working distance plays a significant role when dealing with tasks, tools, and materials. It becomes especially important when you’re handling objects that have different heights or sizes. Being able to see both distant and nearby details can be crucial.Let’s take a look at a few real-life examples:Soldering: When you’re soldering, you need to ensure a safe working environment. This involves having a fume extractor nearby to remove any harmful fumes. You not only need space for your soldering tools like the soldering iron and solder, but also for the fume extractor. Proper working distance helps in arranging these items effectively.Handling Small Samples: Sometimes, you might work with tiny items that are closely packed together. To manipulate these items using tools like tweezers, probes, or pipettes, you need to approach them at the right angle. If the working distance is too short, it might be difficult to access these samples and perform delicate tasks.Variations in Sample Height: Certain materials or samples can have varying heights. In such cases, you need to focus on both the farthest and nearest details. Having a sufficient working distance allows you to adjust your focus to observe the different parts of the sample effectively.In all these situations, the proper working distance ensures that you can work efficiently and safely. It provides the necessary space to accommodate tools, equipment, and variations in the objects you’re working with. This ability to maintain the right distance can greatly enhance the quality and precision of your work.Relationship Between Magnification and Working DistanceThe connection between magnification and working distance is quite interesting. It’s like a seesaw – when one goes up, the other goes down.When you’re using lower magnification, you can keep the lens a bit far from the object you’re looking at. This is called a long working distance. But as you want to zoom in more and make things bigger, you have to move the lens closer to the object. This makes the working distance much shorter.For example, if you’re using really powerful lenses, like the 100x ones, they need to be very, very close to the object. They’re so close that sometimes they need oil to help them see better. But being this close can be tricky – you might accidentally touch and damage the object you’re studying. It’s like getting super close to something delicate. So, it’s important to be careful when using these lenses.Remember, it’s a trade-off: the more you magnify, the closer you need to be to the object. So, when you’re using a microscope, you’re not just looking at tiny things – you’re also figuring out how to balance magnification and distance to see things clearly and without causing any harm. It’s a neat lesson in science and patience!FAQWhat is working distance in a microscope?Working distance in a microscope is the space between the objective lens and the object you’re observing. It’s important because it affects how close you need to be to the object to see it clearly.How does working distance relate to magnification?Working distance and magnification are inversely related. As you increase magnification, you need to move the lens closer to the object for a clear view.Why do some objective lenses require oil immersion for optimal working distance?Oil-immersion lenses, like the 100x objective, need oil between the lens and the slide to achieve maximum clarity. The oil helps capture more details and improve the image quality.Why is longer working distance preferred for some observations?Longer working distance is preferred when observing specimens that are not flat or emit harmful substances. It provides more space and reduces the risk of damaging the object or the lens.What happens if the working distance is too short?A short working distance can make it challenging to manipulate tools and might lead to accidental contact between the lens and the specimen, potentially causing damage.How is working distance measured and indicated on an objective lens?Working distance is usually indicated on the objective lens barrel using the letters “WD,” followed by the distance in millimeters (e.g., “WD: 0.5” or “0.5 EL WD”).Can working distance affect the cost of a microscope lens?Yes, lenses with longer working distances might cost more due to their specialized design and ability to reduce the risk of damage, potentially saving money in the long run.Are there alternatives to oil immersion lenses for achieving short working distances?Yes, some dry objective lenses can provide short working distances without the need for oil immersion, but they may have slightly different characteristics.Why is it important to balance working distance and magnification?Balancing working distance and magnification ensures clear and accurate observations without damaging the specimen or the lens. It’s about finding the right distance for the best results.Can you measure working distance using a digital caliper?While it’s possible to measure working distance using a digital caliper, it’s not recommended as it could potentially damage the lens or compromise your microscope’s performance. It’s safer to rely on manufacturer specifications or inscriptions on the lens barrel.Referenceshttps://www.visioneng.us/resources/articles/working-distance-a-simple-explanation/https://opticsmag.com/what-is-working-distance-in-a-microscope/https://microscopeclarity.com/what-is-working-distance/https://www.e-education.psu.edu/mcl-optpro/theory/node801https://www.olympus-ims.com/en/microscope/terms/working_distance/https://www.rp-photonics.com/working_distance.htmlhttps://blog.microscopeworld.com/2014/08/microscope-working-distance.htmlhttps://www.celestron.com/blogs/knowledgebase/what-is-the-working-distance-of-my-microscopehttps://pages.mtu.edu/~shene/DigiCam/User-Guide/Close-Up/BASICS/Working-Dist.htmlhttps://www.vision-doctor.com/en/optical-calculations/calculation-working-distance.htmlhttps://sciencing.com/difference-between-compound-dissecting-microscopes-5576645.htmlhttps://www.meetoptics.com/academy/working-distancehttps://www.newport.com/f/long-working-distance-objectives

The concept of working distance is very important. Imagine you’re trying to look at something under a microscope, like a tiny object that isn’t completely flat or releases harmful substances. Would you prefer the microscope lens to be really close or a bit far from that object? Of course, you’d want the lens to be farther away. Having more distance between the lens and the object can be very useful when you’re studying things that need space.

Good light indoors can be adjusted by the user to suit their personal needs. A good light system safeguards that these personal adjustments are made within the boundaries of an optimal setting.

By following these steps, you can find out the working distance of an objective lens accurately and safely. Always prioritize the methods that offer the least risk of damage or disruption to your microscope equipment.Why is Working Distance Important?The concept of working distance is very important.

These lenses need to be closer to the light and the object because they have a special quality called “numerical aperture.” When experts make lenses that give you more space to work with (long working distance), they have to make sure they still fix any issues with the lens to make the image clear.Using lenses with longer working distances can also help protect your microscope’s powerful lenses from harm. When lenses are farther away, they are less likely to get damaged. Even though you can be careful when focusing, sometimes accidents happen, and you might bump the lens against the glass slide.So, working distance matters a lot because it helps you observe objects properly, especially when they’re not flat or might be risky to get too close to.

It’s safer to rely on manufacturer specifications or inscriptions on the lens barrel.Referenceshttps://www.visioneng.us/resources/articles/working-distance-a-simple-explanation/https://opticsmag.com/what-is-working-distance-in-a-microscope/https://microscopeclarity.com/what-is-working-distance/https://www.e-education.psu.edu/mcl-optpro/theory/node801https://www.olympus-ims.com/en/microscope/terms/working_distance/https://www.rp-photonics.com/working_distance.htmlhttps://blog.microscopeworld.com/2014/08/microscope-working-distance.htmlhttps://www.celestron.com/blogs/knowledgebase/what-is-the-working-distance-of-my-microscopehttps://pages.mtu.edu/~shene/DigiCam/User-Guide/Close-Up/BASICS/Working-Dist.htmlhttps://www.vision-doctor.com/en/optical-calculations/calculation-working-distance.htmlhttps://sciencing.com/difference-between-compound-dissecting-microscopes-5576645.htmlhttps://www.meetoptics.com/academy/working-distancehttps://www.newport.com/f/long-working-distance-objectives

Good light indoors stimulates during the day with an intensity that is approximately 2-5x higher than the current norm for vision and relaxes during the evening with an intensity that is approximately 5x lower than the current norm for vision.

Consider using a lighting system with a pre-programmed pattern over the day, and that provides the proper light intensity and spectrum at the proper time.

Good Light indoors can be adapted by the user for personal needs based on suggestions by the system. Individuals may differ in light appreciation with respect to intensities and preference for warm or cool tones of (white) light. In addition, individuals can differ in the timing of their sleep-wake phase, also referred to as being a different chronotype. Early chronotypes have a morning preference and late chronotypes an evening preference. This results in individual needs when it comes to the timing of the dynamic 24h pattern of light, and both its intensity and spectral characteristics. In addition, having personal control over the dynamics and spectral characteristics of light is highly appreciated by individuals.

If it is not possible to spend time outdoors, the best alternative is to stay within one meter of a window and regularly look outside.

Use lighting systems that enable you to change the distribution of light in the room during the day, effectively mimicking daylight.

Yes, lenses with longer working distances might cost more due to their specialized design and ability to reduce the risk of damage, potentially saving money in the long run.

Longer working distance is preferred when observing specimens that are not flat or emit harmful substances. It provides more space and reduces the risk of damaging the object or the lens.

Using lenses with longer working distances can also help protect your microscope’s powerful lenses from harm. When lenses are farther away, they are less likely to get damaged. Even though you can be careful when focusing, sometimes accidents happen, and you might bump the lens against the glass slide.

Being outdoor during the day is very important for people. Daytime light intensities outdoor are always higher than indoor, by a factor of anywhere between x10 and x500. And the high light levels outdoor are full spectrum. Sunshine includes infrared (IR) which warms us, and ultraviolet (UV) which when it reaches the skin, supports Vitamin D production, important for calcium uptake for healthy bone structure, and the immune system. The high light intensities we get when outdoors during the day are also important for wellbeing, mood, performance, how we sleep at night and for reducing our sensitivity to light in the evening. Exposure to full spectrum, high intensity daylight in the morning prevents our biological clock from getting out of sync with the natural 24h light-dark cycle. It prevents our body from running late, and from fragmented sleep, waking frequently at night. The Good Light Group advises people to enjoy natural daylight as much as possible by being outside during the day. Because we are not able to be outdoors all day, every day, the Good Light Group has the following recommendations that should be applied at the same time each day, as far as possible:

Guide toBallad

Unless you would like to fall asleep and wake up later, take measures to get a dose of natural daylight in the morning immediately after waking up for at least 30 minutes, e.g. by taking a walk or bicycle ride outdoors, or walking or biking to work or school. If it is dark when you wake, try to ‘see’ the first half hour of natural daylight after sunrise.

While it’s possible to measure working distance using a digital caliper, it’s not recommended as it could potentially damage the lens or compromise your microscope’s performance. It’s safer to rely on manufacturer specifications or inscriptions on the lens barrel.

Although not very common yet, some have reported that it may be beneficial to use a lighting system with additional spectral benefits which can be found in the non-visual part of the spectrum, e.g. supporting Vitamin D production or photobiomodulation.

Use lighting systems that are ‘tuned’ or ‘tuneable’ to support a specific activity. A lighting system is ‘tuned’ if the spectrum is selected to support a specific activity at a specific time of the day. A lighting system is considered ‘tuneable’ if the light spectrum can be changed. ‘Tuneable white’ systems are most common and can vary in Correlated Colour Temperature (CCT). Please note that CCT is only a proxy for spectral content: two light sources with the same CCT can have totally different spectra and therefore a totally different impact on the human non-visual system. The real spectrum is more important than a CCT number. For this reason, you may also choose to use a more advanced ‘tuneable colour’ system. These systems vary not only in CCT, but also in spectral content and in colour.

Consider using a lighting system that offers pre-programmed, task specific light settings to support a range of different activities.
