Abstract

For the first time in Russia, a technology has been developed, using computer-controlled automatic system and a set of special tools, that allows testing and aspherization of off-axis large-sized optical elements of astronomical and space telescopes with a deviation from the nearest sphere up to 20 mm. Computer-controlled process of optical surface figuring is carried out at all stages – milling, grinding and polishing.
