Abstract

LWIR-transmitting materials are of interest for medical, sensing, and communication applications where optical, mechanical and chemical stability during use are essential. Currently available materials are limited to crystalline chalcogenides and halides, chalcogenide glasses, and chalcohalide glasses whose long wavelength transmissivity is obtained at the expense of thermal and quite often chemical stability. This paper reviews preliminary results from an investigation of the glass forming tendencies of a group of compounds that have been chemically designed for optimal transparency in the 8 - 12 micrometers region and that also possess good mechanical and chemical stability.
