Abstract

Cryogenic application of mirrors for laboratory purposes and in spaceborne instruments has caused a rapid increase in the use of metal mirrors in the field of optical engineering. The recently constructed Lockheed Sensor Test Facility (LSTF) uses metal mirrors in cryogenic applications. This article discusses some of the issues involved in the design and fabrication of the LSTF mirrors, such as the problems of material selection, design of mirror shape, and the heat treating process. The final LSTF mirror design and fabrication process are described, as well as the use of the mirrors in the Test Facility and the results of tests performed.
