Abstract

Key features of the opto-mechanical designs for two high performance objective lens assemblies of similar focal lengths and relative apertures, but significantly different configurations and applications are discussed. The first lens is a 25.4 cm EFL, f/1.5 catadioptric lens designed for a ±2.8 degree field and intended for use with a detector array in a spaceborne star mapper. The second example is a 22.8 cm EFL, f/1.5 refractor covering a ±10 degree field intended for distant target observation in an airborne low light level visual periscope and featuring an integral laser channel for target designation and ranging. The logic behind critical materials choices and the techniques applied in mounting the optics in their mechanical surrounds are described.
