The scope of the program was directed to the replication of concave spherical mirrors having a diameter of 4 inches. The objectives of this 6-month program were to procure necessary masters, fabricate, and test approximately 24 replica spheres, continue adhesives and coatings investigation, investigate advanced preform and master techniques, and analyze and specify production processes. These objectives were achieved. An analysis of the replication process was updated, production processes specified, 4 masters received or fabricated, 7 submasters made, preforms procured, adhesives and coatings investigated, fixtures improved, 39 replicas plus 3 replicas by submastering made and analyzed, and the environmental and optical tests described.
