In addition to the possibility of studying objects in transmitted light (classical illumination according to Keller), the following types of studies are carried out using fluorescent techniques on a Micromed 3 LUM microscope: immunochemical, immunological, immunomorphological, immunogenetic.

In the process of researching drugs – blood smears, bone marrow, tissue sections, the following is carried out: detection of latent infections, such as chlamydia, ureaplasmosis, mycaplasmosis, herpes and others; as well as:
• detection of differentiation antigens T and B of lymphocytes, atypical blood cells;
• express diagnostics of bacterial, viral, protozoal, etc. infections;
• determination of antinuclear factor, etc.;
• immunochemical diagnostics of leukemias;
• chromosome analysis.

The microscope includes: a tripod with lamps of light sources, a revolving device for fastening lenses, an object table and a condenser; trinocular head; mercury lamp power supply; set of lenses; eyepieces and filters; Spare parts; accessory kit.

The principle of operation of the microscope is based on the use of the phenomenon of luminescence of observed objects, which occurs under the action of light of a certain spectral composition. Illumination of objects for excitation of luminescence is carried out from above through the opaque window and the objective of the microscope. The light source is a mercury lamp. The light necessary to excite luminescence is separated from the total radiation of a mercury lamp using light filters, conventionally called excitation filters.

The light is directed into the lens by a beam-splitting plate with an interference coating, which mainly reflects the excitation light and transmits the luminescence light of the object. The excitation filter, beam splitter and cutoff filter are combined into a fluorescent block.
