Paper Abstract

A 36-inch f/5 lens and a 24-inch f/3.5 lens used for aerial reconnaissance missions are described. The two lenses are analyzed over their operating temperature ranges, and their performance at ambient conditions and over the operating temperature range is reported. The results indicated that at steady-state the performance of the two lenses is affected only modestly over the operating temperature range when the back focus is compensated by a thermal compensating lens mount.
