Abstract

A 1-m class off-axis SiC aspherical mirror was polished up to 13nm rms with CCOS. The lightweight mirror structure design, CCOS procedure, as well as interferometic test set up are be presented in the paper. In addition, the residual surface error of SiC mirror is analyzed and approach to improve the surface quality is discussed.
