BaF2 window

He Rui optics' BaF2 (Barium Fluoride) window is a transparent optical component made from barium fluoride crystal. BaF2 is known for its excellent transmission 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.

Description

BaF2 windows are commonly used in various optical systems, including:

Ultraviolet Spectroscopy: BaF2 windows are used in UV spectrometers and other UV optical systems due to their high transmission in the UV range.
Infrared Spectroscopy: They are also used in IR spectrometers and Fourier Transform Infrared (FTIR) systems because of their good IR transmission.
Laser Systems: BaF2 windows serve as protective windows for laser cavities and optical paths in laser devices, especially those operating in the UV or IR spectrum.
Optical Communication: In fiber optic communication systems, BaF2 windows can be used for interfaces and other optical components that require UV or IR transmission.
Aerospace and Defense: BaF2 windows are used in sensors, telescopes, and other optical instruments on board aircraft and satellites.
