IR Optical Windows, Φ40.0mm, Thickness=3.0mm, Uncoated, Zinc Sulfide (ZnS), United Optical Technology Co., Ltd (CAT#: STEM-OP-2931-YJL)

IR Optical Windows, Φ40.0mm, Thickness=3.0mm, Uncoated, Zinc Sulfide (ZnS), model 190146, is manufactured by United Optical Technology Co., Ltd.
Zinc Sulfide (ZnS) Windows are parallel plane plates 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 sulfide is an optical material used in the infrared band. It is a yellow chemically inert material with good refractive index uniformity and consistency. Due to its wide transmission band (800-12000nm), zinc sulfide (ZnS) is widely used in the production of infrared optical components such as infrared windows and lenses.
