ABSTRACT:
A body resistant to abrasion and transmissive to light is provided which is formed essentially of zinc sulfide or zinc selenide having incorporated therein small amounts of tellurium. The body can form a layer over zinc sulfide, zinc selenide, or a conventional substrate such as glass. The substrate is thereby protected against fracture and erosion by environmental forces, such as high velocity impact with rain or other atmospheric particles, encountered by aircraft at high speed and over extended periods of time.
