A procedure for constructing a spectropolarimeter of heightened efficiency is considered. It is shown that a limited number of elements can perform functions of the optical reduction, dispersing block, and aberrations corrector. This approach should be of particular assistance in the case of the UV spectral region, where numerous surfaces of traditional spectropolarimeters lead to large losses. We offer a system of spaced dispersing prisms providing the equalization of dispersion, which increases further the efficiency of the instrument in the shortwave spectral region.
