Paper Abstract

Several long wavelength infrared (LWIR) transparent external window materials are compared with respect to their IR bandpass, rain erosion and thermal shock resistance. The materials of interest include: ZnSe, ZnS, multispectral ZnS, calcium lanthanum sulfide (CLS), Ge, GaAs and GaP. Relevant thermal and mechanical property data are presented. The current state of development and size capabilities of each material are also discussed.
