摘　　要：光学镜面复制技术包括镀膜、胶合、脱模等工艺 ,这是一种通过压模的方法生产光学镜面的技术。一个镀好膜的高精度母模的光学面被复制到没有抛光过的复制件非光学表面上 ,母模和复制件之间的面形误差由胶粘剂补偿 ,通过脱模 ,可以得到一个镀好膜的由基体和胶粘剂组成的复制光学面。探讨了光学镜面复制技术的工艺方法 ,给出了所复制的球面、非球面、二次复制平面的干涉图和阴影图。Mirror replication includes coating, gluing and unmolding. It is a technique of producing mirror surface by molding. A coated mirror surface is replicated from a mold with a shape inverse to the required replica to a ground substrate. The distance between the mold and the substrate is filled in by the resin. By unmolding, we can get a coated replica which consists of the substrate and the resin. This paper presents the work on technical methods of the optical mirror replication technique. The testing results of a spherical replica, a concave parabolic replica and two flat replicas are given.
