The objective lens and the ocular or eyepiece lens are in combination responsible for magnification of the specimen being observed.

However, keep in mind that your optical prescription will determine the thickness of the lens. If you have a strong prescription, it is typically recommended to avoid large frames— the larger the frame, the thicker the lens— although this can be minimized with hi-index lenses.

The objective lens is at the bottom of the eyepiece tube and is responsible for both total magnification of the specimen, as well as the resolving power of the microscope.

Wooden frames are made of natural wood, and are available in many different stains. They are also hypoallergenic, as they are made of pure wood, and coated with plant based and natural wood treatments. These frames are super lightweight and comfortable— not to mention stylish. Additionally, wooden frames require little processing and energy to produce, making them an eco-friendly choice.

A drop of special oil which has a similar refractive index to glass, is placed on the cover slip over the specimen.  The oil immersion objective lens is immersed in the oil, rather than air, enabling a clear image of the specimen.

Combined with the eyepiece lens, this lens will provide the lowest magnification power. For example, 10x eyepiece lens, multiplied by the 4x objective lens gives a total magnification of 40x.

The bridge fit is an important aspect that shouldn’t be overlooked. Eyeglasses need to fit on the bridge of your nose so they don’t move or slide down when you bend over or turn your head from side to side. Make sure that the bridge fit is not too small or that it doesn’t sit too high, otherwise it will pinch your nose.

The ocular lens is positioned at the top of the optical tube, while the objective lens is positioned at the bottom. Both of these lenses have important roles in magnification, but the objective lens also has other defined roles, such as resolving power.

The lenses of the microscope are fundamental to its function as they provide the magnification power that allows the microscopic specimen to be seen or observed in greater detail. The two main types of lenses found in light microscopes today are called the objective lens and the ocular lens, which is also called the eyepiece.

Often overlooked is the cleanliness of your optics. Daily use in any environment will attract dust and small debris, and when handling your lens, oils from your body can be transferred. This is particularly the case around the eyepiece.

While style is an important consideration, comfort and durability are also important factors that will directly affect the way you feel while wearing your new eyeglasses.

While the total magnification is determined by both the objective and ocular lens, the resolution is determined by the objective lens alone.

Ensuring your lenses are are kept clean will increase the performance and clarity of your microscope’s images.  There are many products on the market but nothing specifically made for microscopes.  We found a good quality Digital Camera Cleaning Kit was a great option, something with wipes for removing grease and oils and a puffer bottle for blowing away dust.

If you are still uncertain about which eyeglass frames are right for you, ask an eye doctor or optician— they can help you to determine the best fit and most appropriate shape and size to guarantee that you are truly happy with your new frames.

The majority of compound microscopes come with interchangeable objective lenses, which have different magnification powers. This commonly includes 4x, 10x, 40x, and 100x objective lenses.

Since it still provides a good amount of magnification at a good distance from the slide, there is a limited risk of it breaking the glass and potentially ruining the sample. That’s why this objective lens is often preferred before going for a high powered lens.

Eyeglass frames are available in a large variety of sizes— finding a size that suits you should not be too difficult. While you may favor smaller frames for reading glasses, if you will be wearing your eyeglasses all day, a larger frame will provide a larger viewing window and increased peripheral vision.

The majority of light microscopes have an objective lens of some kind, including both compound microscopes and stereo microscopes. Both of these types of microscopes also have an eyepiece or ocular lens.

As previously mentioned, the ocular or eyepiece lens is located at the top of the eyepiece tube and is where you position your eye to observe the specimen. The ocular lens typically has a low magnification (10x) and works in combination with the objective lens to achieve a greater magnification power.

This objective lens will achieve the greatest magnification and has a total magnification of 1000x (10x eyepiece lens x the 100x objective equals 1000).

Because glass and air have different refractive indexes, light bends at different angles when it passes through each of them. When using the 4x, 10x, 40x objective lenses, the light refraction that occurs when looking through the lens to the specimen on the glass slide is not very noticeable. However, when using the higher power objective lenses, for example the 100x, the light refraction is much more obvious.

Light microscopes are relatively complex pieces of equipment in nature with multiple different parts, some which are more complex than others.

Eyeglasses nowadays come in a variety of styles, shapes, colors, and materials— metal, plastic, and even natural wood. Optical stores are filled with rows and rows of frames, manufactured by popular brands and designers to suit every taste and unique fashion sense.

Now that you have chosen the type of frame you are interested in, let’s look at the different aspects of the frame to help you narrow down your choice.

Spring hinges allow the temples to flex outward, without causing any damage— ideal for those who tend to be rough on their glasses or fall asleep with their glasses on. Purchasing frames with spring hinges will decrease the probability that you will need to visit the optical store on a regular basis to adjust or repair your frames.

For example, if you are looking down a microscope, the resolution power relates to the space you can see between two points. A very low resolution would result in a blurred image and would prevent proper observation of the specimen.

The temples connect the front of the eyeglasses to the back of your head, behind your ears. Some temples, called comfort cable temples, wrap around the back of the ears, while other temples are designed without a curve, and put slight pressure on the sides of the head to prevent them from slipping or falling.

For your eyeglasses to fit comfortably without sliding down, the temples must be the correct length for your head size— most frames contain temples that range in length from 120 to 150 mm. If you are not sure if the frame’s temples fit correctly, ask your optical dispenser for help.

Nowadays, metal and plastic frames are made similarly in regards to their durability, weight, and cost. However, the metal composition can vary between frames— so it is important to consult with your eye doctor or optical dispenser before deciding on the winning pair. Also, if you are allergic to nickel, or another type of metal, be sure to look for frames that contain hypoallergenic materials.

Microscope parts and functions

This objective lens is the next lowest powered and is often the most helpful when it comes to analyzing glass slide samples. The total magnification for this lens is equal to 100x magnification (10x eyepiece lens x the 10x objective equals 100).

Plastic frames are fashionable, lightweight and come in a variety of styles and colors. They are also typically less expensive than metal frames. Keep in mind though that plastic frames are not as strong as metal and tend to break more easily.

Rimless frames are also quite popular, especially among those who favor a more subtle look. They are available in a large variety of shapes and sizes— with half rimless frames an option as well.

Resolving power is also a very important metric since magnification power is of little importance if the resolution is not high. Resolution is defined as the ability to distinguish 2 points as two points.

To ensure that you walk out of the store with the most appropriate frames for you, take your time to look through all of the choices, and use this guide to help direct you in your decision.

These frames are lightweight, comfortable, and take the emphasis off the frame itself, as they are nearly invisible. Keep in mind that these frames are more delicate than rimmed frames, and more prone to breaking.

Eyeglass frames are manufactured using different types of materials— some frames are made of purely one type of material such as metal or plastic, while others contain a combination of materials, such as plastic frames with titanium temples.

This objective is often referred to as the scanning objective lens since the low power provides enough magnification to give the observer a good overview of the entire slide and sample.

This is referred to as the high powered objective lens since it is ideal for observing the small details within a specimen sample. The total magnification for this lens is equal to 400x magnification (10x eyepiece lens x the 40x objective equals 400).
