IR Optical Windows, Φ25.4mm, Thickness=2.0mm IR1, Silicon (Si) Single Crystal, United Optical Technology Co., Ltd (CAT#: STEM-OP-2958-YJL)

IR Optical Windows, Φ25.4mm, Thickness=2.0mm IR1, Silicon (Si) Single Crystal, model 190173, is manufactured by United Optical Technology Co., Ltd.
Silicon (Si) Windows are parallel plane panels that are often 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-ready 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.
