It is an intrinsic semiconductor with a band gap of about 2.70 eV at 25°C (77 °F). For more information call: 412-469-8466 (Monday - Friday 9:00 AM -5:00 PM EST) acidic solutions, pH<5, may etch the ZnSe crystal, strong acids will generate toxic hydrogen selenide). It is made into windows and lenses among other components. Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. eCl@ss 38150412 . Prism grade ZnSe exhibits minimal refractive index variations within the material on planes perpendicular to the growth direction as well as in other directions. Company: Angstrom Sciences, Inc. 40 South Linden Street . Due to a very wide transmission range covering 0.6-22 µm chemical vapor deposition grown ZnSe as a high optical quality material is used to manufacture optical components (windows, mirrors, lenses) for high power IR lasers. Zinc Selenide (ZnSe) General Information. It emits blue light when in LEDs. CAS Number: 1315-09-9 / EC Number: 215-259-7 . Linear Formula ZnS . Single crystal ZnSe is available, but is not common but has been reported as having lower absorption and thus more effective for CO 2 optics. Zinc selenide Optical Window, 50.8mm (2.0in) dia x 2mm (0.08in) thick.

Duquesne, PA 15110 . Transportation Information: UN3283, Selenium compound, solid, n.o.s., 6.1, III: Pictogram Signal Word Zinc selenide has a transmission band broader than silicon and germanium. Sheets of amorphous selenium convert X-ray images to patterns of charge in xeroradiography and in solid-state, flat-panel X-ray cameras. ZnSe ZInc Selenide PVD vacuum coating evaporation for precision optics Index variations will test to less than 3 ppm at 0.6328 microns regardless of orientation. Achieving blue light emission from these materials is very unlikely because the particle size needs to be decreased to ultrasmall diameters where stability becomes a great concern. Along with its low absorption in the red portion of the visible spectrum, zinc selenide is ideal for optical systems that combine a 10.6 µm CO 2 laser with a 633 nm HeNe alignment laser. The characteristic color of a ... the range of wavelengths of visible light for which the Zinc selenide is transparent at 0.48 micrometers to .7 micrometers. Zinc selenide Optical Window, 25.4mm (1.0in) dia x 2mm (0.08in) thick. Zinc Selenide is a light yellow crystalline structure. Cadmium selenide was an important component in quantum dots. ZnSe ZInc Selenide PVD vacuum coating evaporation for precision optics These axicons are offered with base angles from 0.1° to 2.0° and are precisely manufactured from zinc selenide (ZnSe), making them ideally suited for mid-infrared laser applications and for use with CO 2 laser applications, like materials processing.
