Propiedades ZNS (Sulfato de Zinc)

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(Chemical vapor deposition) 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.
