Medical trinocular microscopes: a new look at the microworld

Modern medicine and biology are impossible without precise instruments that allow studying microscopic structures. One such device, which has become indispensable in laboratories and clinics, is a medical microscope. 

Microscopy methods depend on the type of sample and research objectives. Modern microscopes combine several illumination methods, which makes them universal tools for scientific and medical research. The choice of illumination method depends on the specific tasks and properties of the material being studied:

1. Bright field method
   In this most common method, a stained or naturally contrasting smear is illuminated from below.
2. Dark field method
   In this case, the researcher sees only the sample illuminated at an angle, and the background remains dark. This method is ideal for studying transparent objects - living cells or microorganisms.
3. Phase contrast detects differences in the phase of light waves passing through a transparent sample, allowing living cells to be observed without staining.
4. Differential interference contrast creates a high-contrast 3D image of thin tissue sections.
5. Polarized illumination is used in industry to study anisotropic minerals and crystals.
6. Fluorescent and ultraviolet illumination study DNA and RNA, which absorb light of a specific wavelength.
7. Confocal illumination uses a laser beam to scan a sample layer by layer and create a high-resolution 3D image.
8. Mineralogy uses oblique illumination, which emphasizes the relief of an object, and reflected light illumination - light is directed through the lens from above, and the reflected light forms an image.

With the development of technology, medical microscopes are becoming more and more sophisticated, and the introduction of 3D visualization and artificial intelligence opens up new horizons for their use.

Microscopes can be made in a classic version - with two eyepieces, and a modified version - with three or more. Additional eyepieces are needed for the assistant's work or for displaying images on the screen. This is especially important in medical research, where it is necessary not only to study samples, but also to document the results for further analysis or training.

For the laboratory diagnostics department, a two- or three-eyepiece microscope is sufficient, other versions are intended for operating rooms. Their wide-field eyepieces with diopter correction provide high resolution and high-quality color rendering, which expands the range of clinical studies.

The versatility of CADUCEUS RESEARCH microscopes makes them an excellent choice for laboratories, educational institutions and research centers.

In addition to the listed lighting methods, microscopes use Keller illumination of the object, which increases the contrast of objects and, as a result, the quality of diagnostics - the doctor can distinguish the details of the cell morphology due to the volume effect. Such microscopes are designed for in-depth laboratory research that requires high image quality. The advantages of Koehler illumination are the uniformity of the field illumination, the removal of artifacts and the maximum resolution of the object due to the correspondence of the apertures of the illuminator and the objective.

Laboratory microscopes CADUCEUS combine the latest technologies in laboratory diagnostics and are an ideal solution for cytological, biochemical, pathological and general clinical research.
