A theoretical study of the dependence of the spectral resolution of acousto-optic filters and the maximum number of resolved elements of acousto-optic deflectors on the radiation wavelength in the range 40 − 100 μ m was carried out. Semiconductor single crystals with a cubic crystal lattice, which are transparent in the considered range, were chosen as the material of acousto-optic devices. It is shown that with increasing wavelength from 40 to 100 μ m, the spectral resolution of the filters increases from 10 to 10 3 , and the maximum number of resolved elements of the deflectors decreases from 10 4 to 10 2 .
