Abstract

In response to technology needs for infrared (IR) telescopes operating at cryogenic temperatures, Eastman Kodak Company has developed a 0.5-meter (m), ultra lightweight, frit bonded, fused silica mirror capable of being scaled to a larger size that would provide a fast aspheric, smooth, low scatter optical surface. This mirror has been evaluated by Kodak at a temperature of 100 degrees Kelvin (°K). This paper reports on a continued evaluation of the mirror jointly by Kodak and Ames Research Center (ARC) to a temperature of 8°K. Analysis of common interferograms by independent processing hardware and software has been carried out by Kodak and ARC. The results of both processes are compared and reported.
