Abstract

Computer Controlled Active Lap(CCAL) manufacture is a new manufacturing technology comparing the classical manufacture and Computer Controlling Optical Surface(CCOS) for large aspheric mirrors manufacturing. The removal function model of active lap is found based on the investigation of active lap structure and working features. After analysis the edge effect, we optimize the founded model through the method of pressure compensation. The mirror surface predicated by the optimized model above basically matches the mirror surface tested by Hartmann-Shack wavefront sensor during the experiments of Φ1300mm(F/2)aspheric mirror manufactured by active lap.
