MgF2 crystal shows good optical and thermal-mechanical properties. The transmission is shard down after 7.0um about 80%, and 10% at 10.um. it is widely used of optical elements such as windows, lenses, and prism in ultraviolet and infrared optical system where extreme durability is required.
MgF2 have a better hardness and short wavelength but easy grinding and polishing compared to CaF2. The surface quality can be reach grade I and the production line can be of grade III. And also it is easy to grow mono crystal and mainly used in VUV and NIR wavelength. So the price has a very litter difference between mono and poly crystal, IR and UV grade. But the growth material is expensive. Therefore the material is most expensive among fluorides crystal.
