    Product Features:

    1. Barium fluoride has good transmission performance in the visible and infrared spectral regions. In optical coatings, barium fluoride can be used as one of the layer materials to improve the transmittance of optical components and reduce reflection losses at the layer interface.

    2. Barium fluoride has a moderate refractive index, which can be adjusted by combining it with other materials to modify the refractive index of optical coatings. This helps achieve specific optical effects, such as reducing light reflection and increasing light transmission.

    3. Barium fluoride has high chemical stability and thermal stability. In optical coatings, barium fluoride can act as a stabilizer, enhancing the corrosion resistance and thermal shock performance of the coating.
