Abstract

The wave front gradient is a key parameter to the low frequency wave front of the aspherical components, which ultimately affects the focusing performance of the optical system. CCOS（Computer Controlled Optical Surfacing）is a technique widely used in precision polishing of aspherical lens. First of all, the reasons for the deterioration of the gradient are analyzed. Secondly, the control technology is designed for various main factors. This paper also found a technological scheme that could inhibit the error of the wave pattern in theory. Finally, combined with the actual conditions of engineering processing, the results of control process methods are verified. The results show that GRMS value of a large aperture（400mm × 400mm）aspheric element is reduced from 0.013 λ/cm to 0.008λ/cm.
