IR Optical Windows, Φ12.5mm, Thickness=3.0mm IR2, Zinc Selenide, United Optical Technology Co., Ltd (CAT#: STEM-OP-2936-YJL)

IR Optical Windows, Φ12.5mm, Thickness=3.0mm IR2, Zinc Selenide, model 190151, is manufactured by United Optical Technology Co., Ltd.
Zinc Selenide (ZnSe) Windows are parallel plane plates that are commonly used as protective windows for electronic sensors or detectors of the external environment. When selecting a window, attention should be paid to the window material, transmittance and transmission band, surface shape, smoothness, parallelism and other parameters.
An IR UV window is a window designed for use in the outer infrared or ultraviolet spectrum. Windows are designed to protect electronic sensors, detectors or other sensitive optical components from saturation or light damage.

Zinc selenide is an optical glass material commonly used in the infrared band. The transmission band is 600nm-16μm. It has the characteristics of low absorption and thermal shock resistance, and is often used in thermal imaging systems. It can also be used in some visible light optical systems and can be used as the substrate for a variety of optical elements, such as lenses, windows, etc.
Note: Special attention should be paid to the fact that zinc selenide is a toxic material. Please be sure to wear gloves when using it and wash your hands after use.
