Method of making durable articles

Optical articles of zinc sulfide and zinc selenide with thick coatings of alumina are disclosed. The alumina coatings are deposited on the zinc sulfide and zinc selenide by a microwave assisted magnetron sputtering. In addition to alumina coatings, the optical articles may also include various polym...
