What is the transmission of BaF2 window ?

BaF2 windows have high transmission in both ultraviolet and infrared regions. They exhibit over 90% transmission in the UV range from around 150 nm to 12 µm and in the infrared range up to approximately 13 µm. These windows are well-suited for optical applications requiring efficient transmission of UV and infrared light.

What is the BaF2 window application ?

Barium fluoride (BaF2) has specific applications in the fields of IR spectrometers, VUV (Vacuum Ultraviolet) applications, and radiation resistance due to its unique optical and material properties:

IR Spectrometers: BaF2 is commonly used as an optical material in IR spectrometers. Its wide transmission range in the infrared region, up to approximately 13 µm, allows it to efficiently transmit infrared light. BaF2 windows and components are employed in FTIR (Fourier Transform Infrared) spectrometers, IR spectroscopy systems, and other analytical instruments that analyze molecular vibrations and chemical structures in the infrared spectrum.

VUV Applications: BaF2 is valuable for VUV applications, which involve the transmission of light in the vacuum ultraviolet region (approximately 115 nm to 200 nm). It has high transmittance in this range, making it suitable for use in VUV optical systems, VUV spectroscopy, and synchrotron radiation experiments.

Radiation Resistance: BaF2 exhibits good resistance to ionizing radiation, making it suitable for use in environments with high radiation levels. It is utilized as a scintillation material in radiation detectors, where it converts incident gamma rays or X-rays into visible light, which can be detected and analyzed.

In summary, BaF2's high transmittance in the infrared and vacuum ultraviolet regions makes it valuable for spectroscopic applications in IR spectrometers and VUV optical systems. Additionally, its radiation resistance makes it suitable for use in radiation detection and measurement devices.
