Rating of the best binocular microscopes for 2022

Who did not dream in childhood to see a drop of rain or a snowflake through a magnifying glass. Modern technologies have made optics affordable and high-precision. Increasing invisible objects to sizes that allow you to see the composition, structure of the sample, observe microprocesses - is this not a fairy tale that has come true. An exciting hobby can grow into a family hobby, and for some it becomes a professional choice. An enlargement device can have a certain set of parameters and vary in characteristics. Here's how to choose the right binocular microscope and live up to your expectations.

Criteria for the right choice

At the initial stage, one should decide on the scope of the tasks facing the researcher.
Depending on the upcoming direction of knowledge, devices can be divided into the following classes:

1. professional;
2. amateur.

Eyepieces

The lens system, which is located on the upper tier of the tube, is directly designed for viewing images. Binocular means a pair of systems for the right and left eyes. Modern models allow you to get a three-dimensional stereo image thanks to two eyepieces and a lens. The three-dimensional image is the main advantage of a stereoscopic or binocular microscope.

Lens

Part of the device, "looking" at the subject of research, is located above the instrument platform. Children's models are equipped with a single lens, more serious amateur and professional series have three or more units. A set of lenses is located in the revolving mechanism, where you can change during the observation. Immersion type with magnification from 40x provides for the use of synthetic oils, distilled water.

According to the type of correction, the entire range of lenses can be divided into classes:

• achromatic ones do not completely eliminate color distortions and are more often used in school and amateur devices;
• apochromatic levels out distortion by 100%;
• planochromatic ones give a clear image with the correction of the curvature of the angle of view, chromatic aberrations and are used when observing large objects;
• semiplanatic ones have distortions along the viewing edge and lower the curvature.

Increase

The magnification parameter of the device is calculated by the formula of multiplying the magnification of the eyepiece by the magnification of the objective. Accordingly, the more eyepieces and lenses the model allows, the more opportunities the microscope has. The useful magnification characteristic is calculated by multiplying the lens diameter by 1000.

Microscope magnification
	Eyepiece 10x	Eyepiece 12.5 x
Lens, x
10	100	125
40	400	500
100	1000	1250

Backlight type

The top location above the subject area is used when studying opaque, translucent samples. The lower illumination is located under the table and serves when observing transparent materials.

Backlight source

In total, there are 4 types of sources:

• 2 lamps - incandescent and halogen;
• mirror;
• Light-emitting diode.

In binoculars, halogen lamps with a powerful stream of white light are more often used, which are subject to regulation according to the degree of illumination.

Diaphragm

The part of the device in the form of a hole, with the help of which the control over the volume of light falling on the object under study is carried out, is called the diaphragm.

A simple type of diaphragm is disc, which consists of a disc with 6 holes of various diameters.

The iris type allows you to set intermediate values ​​and is more common in binoculars.

Focusing

The image accuracy parameter is divided into coarse adjustment within 1 mm and fine adjustment with a range of 0.01÷0.05 mm.

Additional features

Image requirements are changing rapidly.A researcher of any age seeks not only to comprehend the secret processes of the microworld, but also to capture them in a photo or video. The presence of a digital camera allows you to display a picture, dynamic changes on external screens, both television and laptop monitors, PCs.
Of interest is the adapter for smartphones, with which the mobile device is attached to the microscope. In this case, the video eyepiece changes place with the camera, the picture is displayed on the screen. There are special applications for this purpose.

Micropreparations can be purchased in the form of specialized kits with coloring in the necessary solutions, demonstrating the detailed structure of materials and objects.

Price

Children's models can be purchased with a starting price of 4000 rubles. Amateur and professional instruments for laboratories reach the upper price bracket of 160,000 rubles. Specialized optics of the highest class of accuracy and serious capabilities can cost several million rubles.

Errors when choosing

It is important to remember that for children, a magnification of 650x and the presence of a lower illumination will be sufficient.
Binoculars claim to be of a professional level and to equip laboratories where magnification of 1000÷1600x, precise focusing, and a movable object platform are required.

Excellent in all respects, optics from Carl Zeiss, Nikon belongs to the class of highly professional devices and has a price of 1,000,000 rubles.
