Features And Benefits

1. Useful transmission range covers 0.265-10 µm; 2. Fluoride is the most resistant to high-energy radiation 3. The solubility of BaF2 is lower than that of LiF, but it is relatively more soluble than MgF2 and CaF2.

Application

BaF2 is recommended for VUV windows requiring high radiation resistance.
