This paper discusses the optical systems of mirror-lens compensators for monitoring the shape of the primary mirrors of optical telescopes, using as examples the 6-m parabolic mirror of the BTA (Large Azimuthal Telescope), the 1.7-m hyperbolic mirror of the T170 telescope, and the 4.1-m hyperbolic mirror of VISTA (Visible and Infrared Survey Telescope for Astronomy).
