ICC factory grow CaF2 material-15years
Featured Product from Intrinsic Crystal Technology Co., Ltd. (ICC)
1.UV-grade calcium fluoride with low absorption and high transmittance
2.Suitable for 250 nm-7um applications
3.Low refractive index
Calcium fluoride has excellent transmittance between 250 nm- 7um, and is widely used in spectroscopic prism window and lens products. Because of its low absorbance 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. The window sheet of calcium fluoride is made of vacuum ultraviolet grade calcium fluoride and is often used in low temperature imaging system.
