DEVELOPMENT OF LIGHTWEIGHT OPTICALLY ACCURATE REPLICA MIRRORS

Abstract

It was demonstrated that thin rigidized, electroformed, replicas of at least 3 in diameter can be made with surface accuracies sufficient to satisfy the objectives of this contract. Problems in electroforming over vacuum deposited conductive coatings were solved. Criteria for bath temperature and current density control was determined and implemented. he stress phenomena and stress measurement instruments were analyzed. Stress measurement was standardized. Replica thickness variation studies are providing the basic design information required for more accurate replication to be accomplished. Rh coating tests resulted in standardized procedures for Rh plating replicas.
