Abstract

There is a described computer - controlled methods of treatment of large optics with testing of ground surfaces by a set of spherometers and IR-interferometers, testing of lens correctors and CGH correctors, measuring of Radius by a laser tracker on examples of astronomical mirrors production under projects VST, TNT, VISTA, etc. There is a graph describing a degree of complexity of fabricated optics for various telescopes all over the world and there is data about the astronomical mirrors produced in LZOS for different projects.
