A stereoscopic microscope is an excellent tool for chemists, biologists, geologists, radio electronics engineers or jewelers. Conducting scientific research, performing technological operations or repair work, as well as the educational process cannot be imagined without this optical device.
The Russian market is filled with optical products offered by the best manufacturers for use in various fields. For each case, a device with a set of necessary characteristics is required. After all, you can buy a high-quality model at a high price, but the functionality of which will be used to a minimum. To help you choose the right device, our review of the best devices will help.

A stereomicroscope is a high-precision optical device with lenses for multiple magnification of images of small samples or objects with their volumetric perception.
The principle of operation is to connect two microscopes into a single housing, which has different optical paths that focus at slightly different angles on a single point, similar to how human vision works. This allows you to create a three-dimensional volumetric image to analyze the structure and details of the surface.
Features that distinguish stereomicroscopes from other microscopes:
A typical design includes a rack where the main elements are attached.
Optical system of consecutive lenses. Made in the form of tubes, where up to 14 lenses are attached, magnifying the image taken from the surface in front of the lens. As a result, when the first lens magnifies twice, the next one will increase this projection even more. The process continues until the picture is presented on the last lens.
What are:
Lens markings:
A system that projects the display of an object into the eyes. Consists of a group of lenses mounted closer to the imaging plane and an eye group next to the eyes.
They differ in characteristics:
Diaphragm, lens and mirror system to uniformly illuminate the object and completely fill the lens aperture.
Includes items:
The mechanical assembly of a product with a flat surface for fixing or fixing the object of study.
Types of subject tables:
A wide scope of application determines the variety of products that differ in characteristic features.
Image formation is carried out along two symmetrical optical paths, which diverge at a stereoscopic angle. Each system for viewing objects is equipped with a separate lens and eyepiece, has precise centering, and is also combined into one body.
The optical block is equipped with a pair of inverting mirrors or prisms that correct the image orientation to form a correctly oriented image.
Image formation is carried out by two independent parallel optical channels located perpendicular to the plane of the studied sample, with a common objective lens of large diameter. The construction of the structure ensures the projection of the image to infinity for the convergence of optical channels to the focal point of the object plane.
If necessary, which one is better to buy a stereomicroscope, first of all, you need to work out and answer the following questions:
After determining these conditions, you can begin to refine the technical characteristics, the values of which are selected individually according to the purpose of the research:
Selecting the right product for a specific application is a key factor in achieving the desired result. Due to the constant workload of stereomicroscopes in any institution or laboratory, purchasing officials must be confident that they can be easily adapted to any user.
It is important to know what to look for in order to avoid mistakes when choosing.
It is necessary to buy the best inexpensive stereoscopic microscopes in specialized stores selling equipment for the educational process, scientific and medical research, as well as sales offices of well-known manufacturers of optical equipment.
Today, the opportunity is used to order online in an online store that supplies stereomicroscopes. In addition, on the pages of the largest electronic marketplaces Yandex.Market or Ozon.ru, you can find out the necessary information about the product - how much the required product costs, study the description, compare characteristics, find a store and place an order for the product.
In recent years, stereo microscopes have been actively ordered from Ali Express. Numerous positive reviews and recommendations, according to buyers, demonstrate the high quality of the services provided and determine the popularity of the models.
The review presents the best devices on the Russian market, which differ in optical channel construction schemes. Positions were largely determined by the opinions of consumers who use this technique to solve their problems, and not only by the popularity and characteristics of the models.
