ZnSe Windows
Laser Research OpticsRequest Info
Zinc selenide (ZnSe) windows that offer a wide transmission range and can be provided blank, polish-finished or dual-band antireflection-coated for spectrometers and detectors are being introduced by Laser Research Optics.
They operate over a transmission range from 0.6 to 18 µm, have an absorption coefficient of 0.0005/cm at 10.6 µm, and are nonhygroscopic. Highly stable in a laboratory environment, ZnSe windows can be supplied in 0.5- to 3-in. outer-diameter sizes and in various thicknesses to match specific customer requirements.
Chemically vapor deposition-grown, the windows are suitable for systems operating at various bands within the material’s wide transmission range. Typical surface quality in the infrared is 40-20 scratch-dig, 60-40 in the 0.8- to 7-µm region, and 60-40, 80-50 or 120-80 for the 7- to 16-µm region, depending upon system performance requirements.
