Erosion Resistant AR Coatings for IR Windows.

Abstract

Feasibility of rain erosion resistance of two layer AR coatings on ZnS small sample windows with good surface finish has been demonstrated. When exposed to 1 inch/hour simulated rainfalls for 20 minutes at a relative drop impact velocity of 470 mph, transmission losses of about 10 percent occurred. (Author)
