摘要
The invention relates to a method and a device for ultra-precision processing of a Fresnel lens, which describes a non-rotationally symmetric free-form optical surface which is superposed on a plane or curved surface. This is achieved by making the Fresnel lens by turning and planing with a diamond tool.
