CaF2 blanks from ICC factory
Featured Product from Intrinsic Crystal Technology Co., Ltd. (ICC)
UV-grade calcium fluoride with low absorption and high transmittance
It is very suitable for applications between 200nm and 7um.
Low refractive index
Calcium fluoride has excellent transmittance between 200 nm and 7 um, so it is widely used in spectroscopic prism window and lens products. Because of its low absorption and high damage threshold, it has become an ideal choice for excimer laser optics. The low refractive index of calcium fluoride also enables it to be used without antireflective coating. The Knoop hardness of calcium fluoride is 158.3. TECHSPEC < CaF2) window sheets are made of vacuum UV-grade calcium fluoride and are often used in low-temperature thermal imaging systems.
