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

The microscopy method depends on the type of sample and research objectives. Modern microscopes combine several illumination methods, making them universal tools for scientific and medical research. The choice of illumination method depends on specific tasks and the properties of the material under study:

1. Bright Field Method
   In this, the 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 specimen, illuminated at an angle, while the background remains dark. This method is ideal for studying transparent objects - living cells or microorganisms.
3. Phase Contrast reads differences in the phase of light waves passing through a transparent specimen, allowing observation of living cells without staining.
4. Differential Interference Contrast (DIC) Method creates a three-dimensional image of thin tissue sections with high contrast.
5. Polarized Illumination is used in industry to study anisotropic minerals and crystals.
6. Fluorescent and Ultraviolet Illumination is used to study DNA and RNA, which absorb light of a specific wavelength.
7. Confocal Illumination uses a laser beam to scan the specimen layer by layer and construct a three-dimensional image with high resolution.
8. In mineralogy, oblique illumination, which emphasizes the relief of an object, and reflected light illumination are used - light is directed through the objective from above, and the reflected light forms an image.

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

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

For a 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 quality color reproduction, expanding the range of clinical studies.

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

In microscopes, in addition to the listed illumination methods, Köhler illumination is used, which increases the contrast of objects and, as a result, the quality of diagnosis - the doctor can distinguish details of cell morphology due to the effect of volume.

Such microscopes are intended for in-depth laboratory research requiring high image quality. The advantages of Köhler illumination are the uniformity of field illumination, the removal of artifacts, and the maximum resolution of the object due to the matching of the illuminator and objective apertures.

CADUCEUS laboratory microscopes combine the latest technologies in laboratory diagnostics and represent an ideal solution for conducting cytological, biochemical, pathological, and general clinical studies.
