Abstract
This paper proposes a method for designing a catadioptric retroreflector with correction of spherical aberration. The calculation is based on an analysis of the third-order spherical aberration. A concentric meniscus is proposed as a correcting element, the use of which significantly improves the wave front of the output radiation. In this case, a combination of any two glasses with different refractive indices for the given wavelength can be used to correct the aberration.
