Description

technical field [0001] The invention belongs to the field of precision curved surface processing tools. Background technique [0002] Aspherical optical parts are very important optical parts, and the more commonly used ones are parabolic mirrors, hyperbolic mirrors, elliptical mirrors, etc. Aspherical optical parts can easily correct various aberrations, but for spherical optical parts, it usually requires a combination of multiple parts to achieve the same effect. In this way, the use of the aspheric mirror can greatly improve the imaging quality of the optical system and simplify the optical system. Compared with symmetrical aspheric lenses, free-form lenses have greater advantages. There are also many processing methods for free-form surface lenses. Among them, the computer-controlled optical surface shaping (CCOS) technology controls the grinding and polishing head through a specific polishing algorithm, and adjusts the processing parameters according to the processin...
