Paper Abstract

Aluminum honeycomb mirror is an important component of the IR radiant cooler system employing in the aerospace applications. The radiant cooler system has a great impact on the quality of IR measurements. The quality of the mirror affects that of the radiant cooler. This article mainly introduces the manufacture of a large scale replicate mirror using thin film technology on a honeycomb-shaped aluminum plate. It discusses several technical difficulties, such as requisition of the mother board, selection of the glue and the techniques of replication on large scale aluminum plate. Borosilicate glass, which has low index of thermal expansion, is used as mother board material. It is requested to be processed to a good plane, N < or = -5, ΔN < or = 0.3.. After extensive experiments, the type of resin and solidifier and the ratio of those materials are confirmed. The selection is in consideration of the application in outer space condition and for the favor of processing big replicated mirror.
