MSE PRO™ Uncoated Calcium Fluoride (CaF2) Flat Windows, Round Shape

Calcium fluoride (CaF2) window is an optical window typically employed as a protective shield for electronic sensors or detectors in external environments. It possesses a circular shape and allows specific wavelengths of light to pass through while safeguarding the internal instrument from external influences.

Its transmission range spans from 0.13 to 10μm, exhibiting high hardness and resistance to mechanical impact, enabling stability across diverse environments. Additionally, it showcases thermal and chemical stability, allowing for use in high-temperature and corrosive settings.

Precise machining and polishing are essential in the manufacturing process to ensure its shape and optical clarity.

Coating treatments can also be applied to enhance its transparency and anti-reflective properties. Please contact us for customize coating services.
