Zinc Sulfide
Zinc Sulfide
Application
Chemically vapor deposited zinc sulfide (CVD ZnS) is the low lost 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.
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.
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.
Advanced Materials’ CVD ZINC SULFIDE is also available as an evaporative source material. It is supplied in
specified lump sizes (2-20 mm), which to minimize surface contamination, are hand selected to be free from saw
cut, abraded or polished edges.
