Zinc Selenide Window

Zinc Selenide Window

Zinc Selenide Lens(ZnSe Focus Lens) are designed for focusing or collimation applications in the mid-wave and longwave infrared spectrum.

The transmission range of Zinc Selenide ZnSe-CVD is 0.5 - 20 µm. ZnSe CVD used for high power CO2 laser optics at 10.6µm, for protective optics windows or optical elements in FLIR (forward looking infrared) thermal imaging equipment, optics for medical and industrial applications optical plane parallel windows (plates, disks, blanks), wedged windows, Wedge Prism, optical meniscus lens, Spherical Lens and Cylindrical Lens, ZnSe prisms, resonator mirrors of CO2 laser lens.
The refractive index is near 2.4. Zinc Selenide has a very low absorbtion coefficient and is used extensively for high power infrared laser optic. It is non-hygroscopic.

Zinc Selenide (ZnSe) - transparent in wide spectral range from yellow (visible) to far IR. ZnSe material is a chemically inert, non-hygroscopic and highly pure product that is very effective in many optical applications due to its extremely low bulk losses, high resistance to thermal shock and stability in virtually all environments, easily machined.
Special care should be taken when handling Zinc Selenide Lens as it is a toxic material. Always wear rubber or plastic gloves to avoid risk of contamination.

Optical Window is one of the most commonly used optical elements, usually used as the optical view window of sensor, analyzer, or outdoor environment protection, vacuum sealed window etc. China Star Optics offers custom optical window. BK7 Window, Fused silica window, Sapphire window, CaF2 window, Zinc Selenide window, Germanium window, Silicon window etc. precision optical protective windows can be customized. Laser windows range from UV to VIS, NIR, SWIR further MWIR and LWIR are available.

China Star Optics offers high quality custom designed optical windows in any quantity from testing sample to mass production. Extremely small MOQ helps to reduce your initial project investment.
