Posted on: Wed 20 Feb, 2008 7:09 am
Changchun Hengyi Optics Co., Ltd can produce all kinds of optical components with optical crystal materials ( such as calcium fluoride, magnesium fluoride, silicon wafer，quartz wafer, fused silica windows,BaF2,Ge wafer,etc).
Calcium Fluoride
• Greater than 90% Transmission from 250nm-700 nm
• Low Index of Refraction
Calcium Fluoride optics are typically used in spectroscopic windows and lenses due to its high transmission from 250nm to 7µm. Calcium Fluoride is also commonly found in cryogenically cooled thermal imaging systems. Its low absorption and high damage threshold makes it a popular choice for excimer laser optics. Calcium Fluoride's low refractive index allows it to be used without an antireflective coating. The Knoop hardness of Calcium Fluoride is 158.3.
