Barium Fluoride (BaF₂) Rectangular Windows Precision Broadband Optical Windows for UV to IR Applications

Barium Fluoride (BaF₂) Rectangular Windows are commonly used optical components that transmit specific wavelength beams while protecting internal instruments—such as electronic sensors and environmental detectors—from external influences. They exhibit high hardness, resistance to mechanical and thermal shock, and excellent transmittance across ultraviolet, visible, and infrared spectral bands. These windows are widely employed in cryogenic imaging, aerospace systems, and laser optics, and can also be fabricated into lenses, beam splitters, and other optical elements.

The Main Advantages

• Fast scintillation performance
• High transmittance and low absorptivity
• High refractive index and high dispersion properties
