Abstract.   Specific features of design and operation of acousto-optical filters on the base of paratellurite TeO2 crystals are studied. High-aperture singular and double filters designed as headpieces for standard optical microscopes are described.
Keywords:   multispectral microscopy, acousto-optical tunable filter, image processing, paratellurite crystal.
