Abstract

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 the 210 mm diameter flat replica, the 200 mm diameter spherical replica, and the experiment of a concave parabolic replica which we are making. The interferograms of the replicas and some parameters of the experiments are given.
