In a light microscope, a beam of light passes through a transparent or translucent object under study, and the system of lenses and eyepieces magnifies the image of the object. The limit of the resolution of the light device is half the length of the light wave (about 0.3-0.4 μm), which does not allow to see the details of small cellular structures. The advantage of light microscopes is the ability to observe live unicellular organisms in their habitat.

Levenhuk LabZZ M101 - the best budget light microscope
Although the microscope was created for children, the level of technical equipment of the device is relatively high. Adjustable illumination of the lower part of the instrument table using an LED allows you to study transparent and translucent samples (plant cells, protozoa, insect parts).
If you wish to consider a stone or a coin, you can direct the rays of a desk lamp from above to the object. Magnification range from 40x to 640x.
Benefits:
- Democratic price (less than 3 thousand rubles);
- In a complete set for home experiences;
- Low weight (about 1 kg);
- Easy to set up and use;
- Compatibility with digital camera-eyepieces, which makes it possible to take photos and shoot videos of the microworld.
Disadvantages:
- The body is made of high strength plastic;
- Lack of precise focus;
- Optical elements are made from polycarbonate.
Micromed R-1-LED - the best light monocular microscope
The device can be used both in student and in veterinary laboratories. With it, you can study drugs in the form of smears and sections. Thanks to the achromatic multi-layer optics, the image is distinguished by high contrast.
As recommended by the manufacturers, the microscope can be used for hobbies, study and as work equipment. Magnification range from 40x to 1600x.
Benefits:
- Regulatory mechanism for coarse and fine tuning;
- Built-in illuminator with continuously adjustable brightness;
- Two-coordinate table (110x120 mm) with a large range of movement of preparations by 65 and 25 mm;
- Ability to work from 220V and from the built-in battery;
- Simple and reliable design, providing the ability to connect a video eyepiece, optional, and display the image on a PC monitor in real time.
Disadvantages:
- Relatively large weight (3.5 kg).
Biomed MS-2 - the best stereoscopic instrumental microscope
The device allows to obtain a three-dimensional image of the studied drugs and samples. It can be applied in any area where accuracy of work with small objects is important. It can be used by numismatists, phalerists, philatelists, jewelers.
The zoom lenses with variable focal lengths make it possible to magnify the image of the sample 40 times smoothly and comfortably for the eyes.
Benefits:
- High quality stereoscopic image;
- The ability to adjust the interpupillary distance and diopters for the parameters required by the user;
- The ability to conduct research in reflected and transmitted light (each of the lamps is regulated separately);
- The package includes a dust cover;
- The ability to install on the device more powerful eyepieces (optional) with a range of magnification from 60x to 80x;
- Wide-angle eyepieces, giving an increased viewing angle.
Disadvantages:
- There is no possibility to increase the focal length.
Levenhuk 700M - the best microscope with 2000x magnification
This is a microscope for examining transparent samples in transmitted light. The device is a laboratory-level, with broad functionality that can be used at home and in school.
Can be used for general observations, as well as studies of the simplest organisms and bacteria.
Benefits:
- Compatible with Levenhuk digital cameras, which are supplied separately;
- It is equipped with high quality achromatic lenses and an Abbe condenser with an iris diaphragm and filters;
- Equipped with wide-angle eyepieces that extend the viewing angle;

This binocular light microscope with integrated halogen illuminator for transmitted light has a wide magnification range from 40x to 2000x. Power backlight from the network adapter.
High-quality glass optics maintain high image quality. The device can be used at home, as well as in industrial and educational laboratories.
Benefits:
- The presence of coarse and precise focusing and diopter adjustment allows to get a clear focus in each eyepiece;
- The kit includes ready-made micro-preparations;
- The two-coordinate subject table with printed vernier allows you to quickly find the desired fragment even after changing the object under study;
- The Abbe condenser with iris diaphragm allows you to adjust the brightness of the backlight to get the best image;
- It is completed with 3 light filters (red, blue, yellow).
Disadvantages:
- High price (about 27 thousand rubles).
