UV Optical Windows, Φ50.8mm, Thickness=10.0mm, VIS, UV Fused Silica, United Optical Technology Co., Ltd (CAT#: STEM-OP-2872-YJL)

UV Optical Windows, Φ50.8mm, Thickness=10.0mm, VIS,, UV Fused Silica, model 190087, is manufactured by United Optical Technology Co., Ltd.
High Precision UV Fused Silica Windows is a parallel plane plate that is usually used as a protective window for electronic sensors or detectors of external environments. 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 infrared or ultraviolet spectrum. Windows are designed to protect electronic sensors, detectors or other sensitive optical components from saturation or light damage.

UV fused silica glass material has a wider spectral range (185nm-2.1μm) than K9 optical glass. It has excellent transmittance in the ultraviolet band, has a lower refractive index, better uniformity, and a smaller thermal expansion coefficient. It also has higher chemical resistance and very low fluorescence, and can be used to make various optical components, such as lenses, windows, filters, beam splitters, reflectors, prisms, etc.
