ZnSe IR Windows for In-Situ Experiments – Multiple Sizes
Product Description
Zinc selenide (ZnSe) is a yellow transparent polycrystalline optical
material with a broad infrared transmission range of approximately
0.5–15 μm. It is widely used for infrared windows, lenses, reflectors
and other optical components.
ZnSe is especially suitable for optical systems operating around
10.6 μm, including CO₂ laser systems. It can be used for total
reflectors, partial reflectors, beam expanders, plano-convex lenses,
meniscus lenses, gold-coated reflectors, circular polarizers and
field lenses.
CVD ZnSe features very low impurity absorption and low scattering
loss. The material is also resistant to deliquescence and is widely
used in laser systems, medical optics, astronomy, infrared imaging
and laboratory in-situ experiments.
