Study on a New Method of Manufacturing Aspheric Mirror

Abstract

A simple method for manufacturing aspheric mirror. Pour the polymer liquid into a rotating mold. The mold rotates at a constant angular velocity, Stop heating after a period of rotation. The surface of the liquid is parabolic after solidification. This method is suitable for producing embryos of large size aspherical mirror. It can reduce the processing difficulty and reduce the grinding consumption. Relative to existing manufacturing methods, centrifugal molding can greatly reduce processing costs.
