Erosion Resistant FLIR Window Materials.

Abstract

A composite FLIR window has been developed during this program which offers a substantial increase in erosion resistance over that of conventional monolithic windows (germanium or zinc sulfide). This composite consists of a thin (0.060 in.) high durability cladding layer bonded to a thicker (0.400 in.) zinc selenide sublayer. This window also features a segmented aperture design, facilitating window fabrication. Four candidate cladding materials were produced and evaluated with respect to their mechanical, optical and rain erosion resistance characteristics before identifying silicon as the only viable material. Bonding techniques and stresses generated by different thermal expansion remain problem areas that require more development. (Author)
