Computer controlled optical surfacing aspherical lens

Till now the aspherical lens used for high power density laser in China were all made manually. The quality of the lens depended closely on the skill of the craftsman, but CCOS (computer controlled Optical Surfacing) technology does not have this fault. In China, research on CCOS were focused on reflected aspherical mirror and planar mirror, but not on aspherical lens. In this paper, the technology of CCOS fabrication aspherical lens is presented. This technology include analyzing the lens parameter, the style of the machine control, fabrication moving style, parameters used in the experiment, optical testing style, and the experiment achieves the desired results.
