Paper Abstract

Measurements have been made of the IR transmission of several materials at temperatures up to 600°C. The materials measured in the study represent some of the most commonly considered materials for airborne FLIR (forward looking infra-red) sensor windows and missile domes in both the 3-5 micron and 8-12 micron wavebands. All materials show a reduction in overall IR transmission when heated. The general effect is an extension of the phonon absorption band to shorter wavelengths so reducing the waveband over which the material transmits.
