Abstract
This paper describes a telescope with an aperture diameter of 60 cm, for which the mirrors and mirror mounts are being fabricated. The telescope is a three-mirror anastigmat with an offset field and consists of three powered aspheric mirrors made of silicon carbide and two folding flats made of silicon. The mirrors and mirror mounts are being fabricated at the Vavilov State Optical Institute in St. Petersburg, Russia, as part of a collaborative program with the Lockheed Martin Palo Alto Research Laboratories. The designs of the mirrors and mounts, and the results of interferometric tests of the mirrors, are discussed.
