The problem of the development of an adjustable video-spectrometer unit based on an acousto-optic tunable filter has been considered. This unit is embedded into an optical system of microscopes for hyperspectral analysis of microscopic objects. For this purpose, light–energy conjugation of the filter with microscopes is performed. We have calculated the conjugating optical system, which yields an equality of field of view for a wideband and spectral channel. The experimental model of the developed device has been described. Examples of detection for test objects and histological sections along with the calculation results of the spectral parameters for various skin tissues are given. The developed video-spectrometer unit considerably extends the functionality of microscopes and can be widely used to solve various problems of biomedical diagnostics.
