A microscope's primary function is to magnify small objects so they can be seen clearly with the naked eye. It does this by bending or refracting light that passes through a specimen, producing an image that appears much larger than the object's actual size.
Apart from understanding the parts and workings of a microscope, it is also necessary to maintain it properly and carefully. Microscopes are precision instruments, and even a small amount of dust or debris can affect their functioning and the image quality they can produce.
At the top of the microscope, we find the eyepiece or ocular lens. This part of the microscope is where we place our eye to observe the magnified image. The eyepiece has its own magnification power, typically 10x.
The microscope has undeniably been one of the most critical tools in the journey of scientific discovery. Its integration in countless fields, such as biology, medicine, geology, and even art, reaffirms its significance.
Connecting the eyepiece to the base of the microscope is the body tube, an integral structural component. Most importantly, it houses the prism that redirects light up through the eyepiece.
Providing adequate lighting at workstations has many benefits. Daylight contributes to a sense of well-being. A neutral colour of light has a positive effect on concentration, with 4000 K being recommended. On the other hand, the intensity of light adjusted to the work performed increases the efficiency of employees. Therefore, it is reasonable to think about the appropriate use of scientific achievements, such as LED luminaires and the relevant control, so that energy efficiency is combined with productivity.

The world around us is full of intricate details that often go unnoticed due to the limitations of the human eye. Microscopes, with their unique ability to magnify objects, help bridge this gap in our perception and broaden our understanding of the universe, small scale to large. But how does a microscope work? Thatâs a question weâll tackle in this article, diving deep into the world of microscopes.

Annual professional servicing is a good idea if your microscope gets heavy use. This will involve cleaning, lubrication, and alignment checks, among other steps.
Proper lighting of workstations is defined in PN-EN 12464 1. This standard sets out the minimum illumination levels for each activity performed indoors. Moreover, its provisions refer to the required uniformity of lighting and the glare rate at workstations.
The microscope stage, located below the objective lenses, is where you place the specimen or slide being observed. The stage holds the specimen in place and some, called a mechanical stage, can be moved up and down to bring the sample closer to or further from the objective lens.

In a microscope, the prism is used to redirect light. It is housed inside the body tube and it collects the light passing through the specimen and objective lens, then redirects it upwards to the eyepiece or ocular lens, enabling the user to view the magnified image.
A digital microscope has many fun advantages, from high picture quality to the ability to share images. Learn how they work, their cost, and choosing one.

It is also worth taking into account other parameters determining the source of light that can have a negative impact on the comfort of the performed work. It is about the flicker effect, CRI and UGR coefficient, as well as the light colour. These are most often to blame for headaches, bad moods and employee fatigue. Therefore, it is advisable to invest in workstation lighting, where brand-name power supplies are used and the colour rendering is appropriately high.

To clean the lenses of a microscope, use only lens-specific cleaning materials. Rough materials or home cleaning products might cause scratches or leave films that would affect the quality of the image.

In a compound microscope, light emissions from the illuminator pass through the specimen on the stage. This light then goes through the objective lens, which magnifies the image and sends it up through the body tube and the ocular lens for you to view.
Activities involving work at a PC and with documents require great focus. They cause considerable strain on the eyes of workers, so the workplace lighting affects their effectiveness. High contrasts between the work area and the surroundings are not conducive to such work. To this end, general lighting with the appropriate intensity should be provided. It should comply with the relevant standards as well.
Microscope magnification is achieved by multiplying the magnification of the objective lens by the eyepiece lens. For example, if you're using a 10x eyepiece and a 40x objective, you will get an overall magnification of 400 times.
Every workplace should be properly illuminated and, given the tasks to be performed, the light intensity in the office is particularly important. Proper lighting has a positive effect on employees and increases their efficiency. This can be achieved by using energy-efficient solutions, such as LED luminaires.
Illumination is key in any optical instrument. The light source or illuminator, located below the stage, is there to shed light on the specimen. This not only allows us to see the specimen but also forms the image that is then magnified by the lenses.

Microscopes are not just about magnification; they also resolve the image. Resolution is the microscope's ability to distinguish two points on a specimen as separate entities, ultimately determining the clarity of the image. We commonly think of this as focus.

For office work, where tasks are performed mainly at a PC, it is necessary to ensure that the light falling on the work surface is at least 500 lx. However, in places where computer equipment is used occasionally, the ligh intensity should be at least 300 lx. The table below also shows other examples of activities performed in office work and the respective light intensity required.
Before understanding how a microscope works, it is helpful to understand the parts of a microscope. The microscope is made up of several components, each playing a unique role in the image projection process.
Another crucial part of the microscope is the objective lens. Located at the other end of the body tube, the objective lens is much closer to the specimen being observed. There are sometimes three or four objective lenses on a rotating turret, each providing different magnification levels, ranging from 4x to 100x.
Also, never try to force any mechanical parts to move. If something seems to be stuck, consult the instruction manual or contact a professional. One common error of novice users is forcing the stage too far and breaking the slide against the objective lens.
While modern technology has introduced more complex types of microscopes, like scanning electron microscopes or atomic force microscopes, the essential principle remains the same â magnify the small things to help us better understand the microscopic world around us.
Office buildings are workplaces where employees spend a significant amount of time, but they often lack daylight. Companies also work at night, so it is necessary to use artificial light sources. Electrical lighting should be adapted to the prevailing conditions and the type of work performed.
Understanding the structure and functionality of a microscope is not just intriguing, but it also helps users maintain the instrument and troubleshoot basic issues.
In sum, understanding how a microscope works is not only fascinating but also contributes to a greater understanding and appreciation of the significant impact this tool has made on our world. Whether you're a student grappling with your first lab assignments or a professional scientist exploring the frontiers of your field, the microscope is indeed a key to a universe unseen.
