Paper Abstract

The technical capabilities of LZOS allow optics manufacturing from the phase of melting and annealing of Astrositall® blanks to their final figuring. Nowadays LZOS is working on the several large contracts, among them are manufacturing of 96 hexagonal segment blanks of 1019 mm x 55 mm of Sitall CO-115M for the SALT (Southern African Large Telescope) primary segmented mirror, and 40 sub-mirrors of Zerodur® for the 6.7 m x 6 m segmented Mb mirror for the LAMOST (Large Sky Area Multi-Object Spectroscopic Telescope) project.
