Infrared Window Alternative--CVD ZINC SULFIDE

Chemically vapor deposited zinc sulfide (CVD ZINC SULFIDE) is the low cost alternative for infrared windows, domes and optical elements. With a fracture strength double that of zinc selenide, and high hardness, zinc sulfide has been used successfully in many military applications requiring mechanical resistance to hostile environments. Missile domes and external windows for military aircraft have been produced by Advanced Materials' CVD ZINC SULFIDE as the mechanical features of this material allow for high resistance to rain and dust. Its low cost also makes it attractive for commercial applications.

SUMMARY:

DESCRIPTION:

Advanced Materials' CVD ZINC SULFIDE is chemically inert, non-hygroscopic, highly pure, theoretically dense and easily machined. Like zinc selenide, zinc sulfide displays a high level of index of refraction homogeneity and offers imaging uniformity across the 8-12 micron waveband. This material also transmits in the mid-wave IR region, but with higher absorption and scatter as the wavenumber increases.

AVAILABLE FORMS:

Custom diameters, rectangles, CNC-profiled blanks, generated lens blanks, prisms, and near-net shape domes can be made to your specifications. Sheet material is also available.

EVAPORATIVE SOURCE MATERIALS:

Advanced Materials' CVD ZINC SULFIDE is also available as an evaporative source material. It is supplied in specified lump sizes (2-20mm) which to minimize surface contamination are hand selected to be free from saw cut, abraded or polished edges.
