Abstract

The optical materials available for the construction of a universal thermal imaging lens effective over the complete passband of germanium from 2 to 13 microns are considered. Suitable material combinations are suggested for the design of simultaneously achromatic and athermal objective lenses. The performance of some examples is compared with that available from narrow band germanium optics.
