Znic Selenide ZnSe Windows Product Attributes
Zinc Selenide (ZnSe) windows has low IR absorption, and is transparent across a very wide 0.6-16 μm spectral range. ZnSe crystal belongs to a kind of Optical Crystal, but Znic Selenide IR Windows are usually used as a kind of Optical Windows. The optical windows is advantageous for thermal imaging, where temperatures of remote objects are ascertained via their blackbody radiation spectrum. Long wavelength transparency is crucial for imaging room temperature objects, which radiate at peak wavelength of approximately 10 μm with very low intensity. Zinc Selenide (ZnSe) as a optical laser and it has a high index of refraction which requires an anti-reflection coating to achieve high transmission. Our broadband AR.20 coating is optimized for 3 μm to 12 μm. ZnSe windows are an excellent choice of Optical Element for a variety of IR applications including high power CO2 laser systems. Zinc Selenide offers low IR absorption, and high resistance to thermal shock. However, windows must be handled with caution due to material's softness. As a kind of aser component , you can customise Zinc Selenide (ZnSe) products to your needs. We can also provide Optical Filters, beamsplitter, optical mirror and optical prism with Zinc Selenide (ZnSe). Applications of Zinc Selenide (ZnSe) as below: Ideal for high power CO2 laser applications; Extremely low IR absorption; Highly resistant to thermal shock; 3 to 12 μm broadband IR antireflection coating; Soft material not recommended for harsh environments; Low dispersion and low absorption coefficient. If you do not find suitable specifications for your application please contact us for custom solution. Coupletech also provide Laser Component, Pockels Cell Driver, Optical Element and Polarization Optics.

The Brewster window uses the material's total-reflection properties. At the specified incidence angle, known as the material's Brewster angle, the S-polarized component is partially reflected while the P component is nearly fully transmitted. Sunday offers various UV fused-silica Brewster windows for ultraviolet applications.

An optical dome is a lens element with two concentric spherical surfaces. Common materials include K9 glass, fused silica, ZnS and ZnSe, with parallelism tolerance controlled within 2μm. Typical shapes are hemispherical or hyperhemispherical. Widely used in detectors, optical sensors, underwater photography and security monitoring, domes protect internal optics, provide a wide-angle light-entry window and optimize optical transmission.
