...Weisi Li; Ping Zhou; Zhichao Geng; Ying Yan; Dongming Guo To improve the efficiency of flat optics fabrication, a global correction method with the patterned polishing pad is developed in this paper. Through creating grooves on a polishing pad, the contact pressure distribution on the optics...

... the flatness of a rough quartz sample since the laser interferometer measuring device restrictions. Mist-abrasion machining method is proposed for corrective figuring of the optical materials. By the new figuring method, not only the polishing time decreases but also its efficiency increases by bigger abrasive...
