Calcium Fluoride Round Windows

Calcium Fluoride Windows（round）

Calcium fluoride round windows have excellent UV and infrared transmittance. The optical wavelength is 0.13 microns in vacuum ultraviolet and 10 microns in far infrared, including five levels: IR infrared, VIS visible, UV ultraviolet, VUV vacuum ultraviolet, and quasi molecular level. Used to separate the environment on both sides, isolating the interior and exterior of the instrument, and protecting internal components. It has a high laser damage threshold and is used to produce optical components for excimer lasers, mobile phone lenses, camera lenses, infrared sensor windows, temperature measurement observation windows, etc. High hardness, strong resistance to mechanical and thermal shock, good seismic resistance and thermal shock resistance, as well as good mechanical processing performance. UM OPTICS can provide different types of window sheets such as circular, rectangular, wedge-shaped, perforated, and stepped sheets.
