ZnS materials have two grades and can be use in imaging systems. Regular grade material is grown by the chemical vapor deposition process. This material is often used in the 3um to 5 um and 8um to 12 um region. It has reasonable hardness and is moderately priced.
Multi Spectral grade ZnS (CLEARTRAN ZnS) is treated after growth to eliminate microscopic voids and defects which occur in the regular grade, thus extending the usefulness of this material to include the visible region.
Compared with zinc selenium (ZnSe), zinc sulfide is lower priced and harder, more resistant to inclement weather, with fracture strength two times that of zinc selenium, thus making it an ideal material for production of missile radome and infrared winder for military aircrafts.
