Abstract

The goal of investigation is to estimate the quality of the mirror-lens telescope (MLT) consisting of the afocal two-mirror system (ATS) and the lens. Such combination can decrease size and mass of the telescope. This aspect greatly influences the application of device in the outer space. Optical computer programs used nowadays do not allow calculating oblique beams in the systems with surfaces defined parametrically. In the work the task of calculation of oblique beams in such kind of systems was solved and the computer program was composed.
