CaF2 (Calcium Fluoride) window


He Rui optics' CaF2 (Calcium Fluoride) window is a transparent optical component made from calcium fluoride crystal. CaF2 is known for its excellent optical properties across a wide range of wavelengths, including ultraviolet (UV), visible, and infrared (IR). It is particularly useful in applications that require transmission in the UV and IR regions of the spectrum.

     CaF2 windows are commonly used in various optical systems, including:

  1. Ultraviolet and Infrared Spectroscopy: CaF2 windows are used in spectrometers and other optical systems that operate in the UV and IR range due to their high transmission in these regions.

  2. Laser Systems: They serve as protective windows for laser cavities and optical paths in laser devices, especially those operating in the UV or IR spectrum.

  3. Optical Communication: In fiber optic communication systems, CaF2 windows can be used for interfaces and other optical components that require UV or IR transmission.

  4. Aerospace and Defense: CaF2 windows are used in sensors, telescopes, and other optical instruments on board aircraft and satellites.
