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.
