Abstract:

Subject of study. Method for calculating the multispectral module for a microscope. The aim of the work is to develop and validate a multispectral device compatible with a standard optical microscope and providing simultaneous acquisition of spectral images of a microobject. Method. The multispectral camera consists of identical miniature lenses simultaneously forming images of the same object on different parts of a single matrix sensor. Spectral filtering is performed by narrow-band light filters installed behind each lens. Optical coupling of the multispectral camera and microscope is performed by using a special coupling system. Main results.  The optical system of the multispectral module forming 8 spectral images of the same object on a single sensor in the spectral range of 450–800 nm is calculated. The multispectral module is manufactured. The correspondence of theoretically calculated and experimentally obtained image quality indicators is shown. Practical significance. The developed multispectral module can be applied both for spectral imaging and for the analysis of the spatial distribution of spectral properties of various microobjects. Scanning is not used to obtain spectral images, which allows the module to be used also for the study of fast processes or for the registration of weak signals with long exposures.
