Optical, mechanical and erosion protective characteristics of boron and gallium phosphide have been evaluated as single films and within anti-reflection multilayers. These coatings are shown to combine broad-band infra-red transmission with environmental durability, specifically in relation to abrasion resistance and elevated temperature performance up to 500 degree(s)C. Rain erosion protection of all common IR optical materials is demonstrated from single water jet impact and whirling arm tests. Protective characteristics in relation to solid particle impact are described. Productionizing of phosphide coating processes is well advanced in relation to control, scaling and handling of hazardous feedstocks.
