CVD Zinc Sulfide/Zinc Sulfide Optical Lens/Zinc Sulfide Machining/Zinc Sulfide Optical Windows

Description

General Introduction: CVD Zinc Sulfide
CVD Ceramics' chemically vapor deposited CVD Zinc Sulfide is the low cost alternative for infrared windows, domes and optical elements. With a fracture strength double that of zinc  Sulfide and high hardness, zinc sulfide has been used successfully in many military applications requiring mechanical resistance to hostile environments. Cleartran is a form of CVD Zinc Sulfide material that is modified by a post-deposition hot isostatic process. This process removes zinc hydrides from the crystal lattice, normalizes crystal structure and purifies the material, all contributing to single crystal-like transmittance in the visible through far infrared ranges (0.35 -14 microns). With its low absorption and scatter throughout its broad transmitting range and high optical quality, is particularly well-suited for multi-spectral applications that require a single aperture for beam path for several wavebands.
CVD Zinc Sulfide and Cleartran are chemically inert, non-hygroscopic, highly pure, theoretically dense and easily machined.
Custom diameters, rectangles, CNC-profiled blanks, generated lens blanks, prisms and near-net shape domes can be made to your specifications.
CVD Zinc Sulfide usually is used in VIS/IR applications

, etc.
Main Characteristics:
1).Its breaking strength is twice that of ZnSe, and its hardness is very high;
2).Excellent mechanical properties make it highly resistant to rain and dust
3).Its low cost also makes it very attractive for business and application
4).The chemical properties of CVD ZnS are inert
5).It has non hygroscopicity and high purity
6).Theoretically very compact and easy to machine
7).Same to ZnSe, ZnS exhibits high refractive uniformity and provides imaging uniformity over the entire 8-12 micron band
8).This kind of material can also transmit in the medium wave IR region, but with the increase of wave number, its absorption and scattering begin to increase
9).It can be used as a source of evaporation
10).It can maintain its stability under almost all environmental conditions.
11).Round blanks and sheets are available in stock to meet your urgent needs
