Abstract
In this paper, the manufacturing and testing procedures to make large off-axis aspherical mirrors are presented. The difficulties in polishing and testing for both circular aperture and rectangular aperture mirrors are previewed, and a possible solution is given. The two mirrors have been polished by means of CCOS, the final accuracy is 25-nm rms for 770-mm x 210-mm rectangular mirror and 20-nm rms for (phi) 600-mm circular mirror. These results just meet the optical tolerances specified by the designer, and the manufacturing and testing procedures presented here show good ability to make large off-axis aspherical mirrors.
