SPECTROSCOPIC HEAD FOR DIGITAL OPTICAL UNIT OF DEVICE FOR IDENTIFYING MICROORGANISMS IN ANALYSED BIOLOGICAL SAMPLE Russian patent published in 2024 - IPC G01N21/64 

FIELD: laboratory equipment.

SUBSTANCE: invention relates to laboratory equipment for microbiological research. Spectroscopic head for a digital optical unit of a device for identifying microorganisms in an analysed biological sample includes a holder and two optical systems arranged in the holder, configured to input and output optical radiation in orthogonal planes, one of which is for supply of exciting radiation, second – for detection of signal of fluorescent response from biological sample. Each of the optical systems contains optical fibre placed in the light guide channels, two convex lenses – input and output, and a flat mirror located on the optical path between the lenses, and the holder is assembled from at least three parts having adjacent shaped surfaces configured to form, when parts are aligned, of two light-guide channels to accommodate said optical systems.

EFFECT: invention provides higher reliability, compactness, simplified assembly.
