Chemically vapor deposited CVD Zinc Selenide is the material of choice for use as optical components in high powered CO2 lasers due to its low bulk absorption at 10.6 microns. Its index of refraction homogeneity and uniformity offers excellent optical performance for use as protective windows or optical elements in high resolution forward looking (FLIR) thermal imaging equipment. This material has also been used as small windows and lenses in medical and industrial applications, such as thermometry and spectroscopy.
CVD Zinc Selenide is chemically inert, non-hygroscopic, highly pure, theoretically dense and easily machined. It has extremely low bulk losses due to absorption and scatter, has a high resistance to thermal shock and is stable in virtually all environments.
Custom diameters, rectangles, CNC-profiled blanks, generated lens blanks, prisms and near-net shape domes can be made to your specifications.

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.

Infrared filter thermometer is composed of photodetector, optical system, signal processing, signal amplifier, display output, feedback source and radiation of the measured object.

This material was developed by OHARA based on our knowledge of High Homogeneity melting and Precise Crystallization. This material is produced under tightly controlled conditions and offers outstanding thermal, mechanical and chemical properties.

H-K9L crystal is also called H-K9L glass, which can also refer to glass products made of H-K9L material, which are used in optical coating and other fields. The light transmittance, refraction effect, hardness and texture are much higher than those of resin materials.
