IR Optical Windows, Φ25.0mm, Thickness=5.0mm, Uncoated, Calcium Fluoride (CaF2) Single-Crystal, United Optical Technology Co., Ltd (CAT#: STEM-OP-2919-YJL)

IR Optical Windows, Φ25.0mm, Thickness=5.0mm, Uncoated, Calcium Fluoride (CaF2) Single-Crystal, model 190134, is manufactured by United Optical Technology Co., Ltd.
Calcium Fluoride (CaF2) 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.

Calcium fluoride material has a wide transmission spectrum range (180nm-8.0μm). It has the characteristics of high damage threshold, low fluorescence, high uniformity, etc. It has soft physical properties and the surface is easy to scratch. It is often used in the collimation of lasers and is often used as the substrate for various optical components, such as lenses, windows, etc.
