Paper Abstract

Ultra-hard multilayer anti-reflection coatings possessing a wide optical band-width have been developed for the common IR transmitting substrate materials. Coatings have been produced using RF plasma assisted chemical vapour deposition from a variety of feedstocks. All the coatings possess excellent abrasion resistance - on a par with that of diamond-like carbon, when assessed in a wiper test using a sand/water slurry. The coatings all exhibit excellent resistance to the effects of rain erosion. The best of these coatings on zinc sulphide substrates for 8-12μm, when tested in the whirling arm erosion rig at RAE, Farnborough, exhibited a higher level of protection than any other coating or substrate material ever tested there.
