Abstract

This paper reports the experiment results of ultrathin hexagonal optical flat (a small sample of LAMOST M_A submirror, its diagonal is 310 mm with a thickness of 7 mm), on (Phi) 1M annular continuous polisher, and its merit, technology, testing method and testing result (rms < 0.03(lambda) ). This paper also analyzes the questions that exist in processing now and suggests to build processing and testing equipment, if we prepare for polishing 1100 mm M_A submirrors of LAMOST.
