This paper discusses mirror systems with an intermediate image after reflection from two mirrors, calculated for the region of third-order aberrations. The goal of this study is to search for versions with corrected distortion and acceptable values of the relative aperture of the primary mirror and the screening of the entrance pupil. The study is carried out for systems with a relative aperture of 1:6 and an angular field of 2ω=2°. A comparative analysis of mirror and mirror–lens objectives with identical optical characteristics is carried out.
