Abstract

Mass production of high order aspherical lens can only use CNC fabrication system. The moving tools belong to CNC system can only be controlled by scattered point. To make manufacturer easy to fabricate high order aspherical lens, it should keep surface smooth that's means there is no sharp oscillation of tool during working process. Generally, the smoothing surface is of c¹ and c² continuous. It is known that c¹ ad c² continuous standing for height sequence and radius sequence of special point sequence in different direction are continuous. In this paper, we introduce a method to judge surface smoothing and propose a method to prevent high order aspherical lens surfacefrom being bad smoothingness. This method proves mess production by Mason optics for several years.
