Abstract

Infrared coatings are required on both surfaces of infrared domes to increase transmission and enhance system performance. These domes are integral parts of either a Missile System or an electro-optical sensor attached to military vehicles. The convex surface ofthe dome is exposed to the harsh environment ofthe outside world, and therefore requires a coating which not only increases transmission but is able to withstand humidity, fluids, exhaust, sand and rain environments. This paper deals with the techniques that were developed to adapt a rain erosion resistant coating for ZnS Optical Flats Windows to curved surfaces. The fabrication process testing and results are described in this paper.
