UV Optical Windows, Φ12.5mm, Thickness=2.0mm, Uncoated, Optical Grade Sapphire, United Optical Technology Co., Ltd (CAT#: STEM-OP-2908-YJL)

UV Optical Windows, Φ12.5mm, Thickness=2.0mm, Uncoated, Optical Grade Sapphire, model 190123, is manufactured by United Optical Technology Co., Ltd.
High Precision Sapphire Windows is a parallel plane plate that is usually used as a protective window 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.
Infrared UV windows are windows designed for use in the infrared or ultraviolet bands. Windows are designed to protect electronic sensors, detectors or other sensitive optical components from saturation or light damage.

Sapphire has high surface hardness, high thermal conductivity, high dielectric constant, and resistance to chemical acids and bases. Since sapphire is second only to diamond in hardness and its structural strength is very high, the thickness of sapphire windows made through enhanced light transmittance is thinner than ordinary high-dielectric windows.
