The Process and Techniques of Manufacturing Replica Mirrors (Cast Epoxy)

Abstract

This report is concerned with improving the techniques of making replica mirrors as reported in 'The Process and Techniques of Fabricating Replica', F.A. Report PP-T-2520-1 by Robert P. Hogan, Nov. 1967. The process involves the reproduction of a polished mirror surface, in the form of a thin film epoxy casting complete in all details, on an aluminum preform. Double replication, used in this study, is a two stage process whereby an inverse replication of a master mirror surface is cast on a submaster, and is then conversely replicated on an aluminum preform. The epoxy, after proper vacuum coating, becomes the mirror, and the aluminum provides stability, rigidity and strength.
