Rating of the best stereomicroscopes for 2024

A stereoscopic microscope is a great tool for chemists, biologists, geologists, electronics engineers or jewelers. Scientific research, technological operations or repair work, as well as the educational process cannot be imagined without this optical device.

The Russian market is full of optical products offered by the best manufacturers for use in various fields. Each case requires a device with a set of required characteristics. After all, you can buy a high-quality model at a high price, but the functionality of which will be used to a minimum. Our roundup of the best devices will help you choose the right device.

General information and purpose

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 combine two microscopes into one housing, which has different optical paths that focus at slightly different angles to a single point, similar to the functioning of human vision. This allows you to create a 3D volumetric image for the analysis of structure and surface details.

Applications

• in the education system as a teaching apparatus for practical and laboratory work in biology, chemistry, botany, zoology, entomology, etc .;

• scientific research in chemistry, geology, oceanography, metallurgy and other fields;

• in medicine for daily research, analyzes, fundamental experiments, and also as a dental device;

• in forensic medicine for examinations;

• in the system of life safety and health protection to control the quality of water, food, medicines;

• in industry to control the assembly of electronic components;

• in jewelry production for the analysis and verification of products;

• in agriculture, breweries and wineries for product control;

General device

A typical design includes a rack where the main elements are attached.

Lenses

Optical system of consecutive lenses. They are made in the form of tubes, where up to 14 lenses are attached to increase the image taken from the surface of the lens in front. As a result, at 2x magnification with the first lens, the next will magnify this projection even more. The process continues until the picture is presented on the last lens.

What are:

• by design quality:
  • achromatic - use within the spectrum from 486 nm to 656 nm with obtaining a bluish-reddish image;
  • apochromatic - obtaining a clear image with accurate color reproduction;
  • flat field (plano lenses) - sharp picture for the entire field of view;
• by parametric characteristics:
  • tube with limited size (160 mm) or to "infinity";
  • magnification up to 10x (small), up to 50x (medium), more than 50x (large) or more than 100x (extra large);
  • apertures up to 0.25 (small), up to 0.65 (medium) or over 0.65 (large);
  • working distance is increased, long or extra long;
  • linear field up to 18 mm (normal), up to 22.5 mm (wide), or more than 22.5 mm (extra wide);
  • standard height (33 or 45 mm) or non-standard;
• by design features:
  • without a springy frame or with a springy frame;
  • without or with a corrective frame;
  • with an internal iris diaphragm;
• by research methods:
  • without or with a cover glass;
  • in reflected or transmitted light, polarizing, phase, luminescent;
  • non-immersion or immersion.

Lens markings:

• magnification value (times, x-krats) - 20x, 50x;
• aperture - 0.55;
• research methods: phase (F), polarization (P), luminescent (L), phase-luminescent (PL), epiolens (EPI);
• correction: apochromatic (APO), planachromatic (PLAN), planapochromatic (PLAN-APO).

Eyepieces

A system that projects the display of an object into the eyes. Consists of a lens group installed closer to the imaging plane and an eye group near the eyes.

They differ in characteristic features:

• no compensation or compensatory action;
• the field is normal or flat;
• wide-angle (eyepiece number greater than 180) or ultra-wide-angle (greater than 225);
• with extended pupils to work with glasses;
• for projection, photography;
• with or without internal guidance.

Lighting

A system of diaphragms, lenses and mirrors for uniform illumination of the object and full filling of the lens aperture.

Includes elements:

• a collector that increases the size of the luminous body;
• a condenser that increases the luminous flux.

Subject table

Mechanical unit of the product with a flat surface for fixing or fixing the object of study.

Types of stage:

• motionless;
• coordinate;
• rotating:
  • not centered;
  • centered.

Classification

The wide scope of application determines the variety of products that differ in characteristic features.

By sight

1. Digital.
2. Analog.

By type of magnification change

1. Constant - for the simplest devices.
2. Step (discrete) - simple switching of the optical mechanism handle.
3. Smooth (zoom, pancratic) - for modern universal products.

By optical scheme

Grenou's scheme

Image formation is carried out along two symmetrical optical paths that diverge at a stereoscopic angle. Each system for viewing objects is equipped with a separate objective and eyepiece, has precise centering, and is also combined into one housing.

The optical unit is equipped with a pair of wrapping mirrors or prisms that correct the image orientation to form a correctly oriented image.

• excellent depth of field and stereoscopicity;
• ease of correction of optical aberrations;
• compactness;
• low cost.

• keystone distortion of the picture.

Abbe's scheme

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 provides the projection of the image to infinity for convergence of the optical channels to the focal point of the object plane.

• large aperture;
• high accuracy of research results;
• good correction of optical aberrations;
• improved resolution;
• accurate color reproduction;
• additional accessories and sets for polarization, fluorescence, heated tables.

• significant dimensions;
• lack of visual sensation of a three-dimensional image;
• high price.

Criterias of choice

If necessary, which one is better to buy a stereomicroscope, first of all, you need to work out and answer the following questions:

• why do you need such a device;
• what objects need to be examined, visualized or fixed;
• how long will it take to use the product;
• financial capabilities that determine the types of models - budget or luxury class.

After determining these conditions, you can proceed to clarify the technical characteristics, the values ​​of which are selected individually for the purpose of the research:

• total magnification, the value of which is the sum of the indicators of the regulator, objective and eyepieces;
• zoom block (regulator). Popular models provide 16x (zoom block) in the 20.5: 1 range and also have the necessary elements for accurate measurements;
• depth of field;
• object field, depending on the degree of magnification. Eyepieces with 10x have a visible field value (F.N.) of 23, i.e. with a single increase it will be 23 mm in diameter, and with a threefold increase it will decrease by a third and will be 7.66;
• quality optics with a high degree of aberration correction;
• working distance from sample to lens. With increasing magnification, it decreases;
• ergonomic parameters for comfortable work;
• correct definition of lighting:
  • falling - for all opaque objects;
  • passing - when studying transparent samples;
  • bright field of transmitted light - for studying high-contrast objects;
  • passing oblique - when studying colorless materials;
  • dark field - the use of a special tripod with mechanisms for redirecting light at an oblique angle;
  • contrast for transparent materials - to display refractive index changes using brightness.

Choosing the right product for a specific application is the main 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 are easily adaptable to any user.

It is important to know what to look for in order to avoid mistakes when choosing.
