ABSTRACT:
An electro-optic system 10 is described which comprises an infrared sensor 12 and a processing unit 14 protected by a protective infrared transmissive window 16. The window 16 comprises a substrate layer 18 which may comprise gallium arsenide, zinc selenide, zinc sulfide or germanium. A protective layer 22 of gallium phosphide is formed outwardly from the substrate layer 18. An anti-reflective coating 20 is formed inwardly from substrate layer 18 and an outward anti-reflective coating 26 is formed outwardly from protective layer 22. The incorporation of protective layer 22 allows for excellent impact and wear resistance without interfering with the optical characteristics of the protective window 16.
