Calcium fluoride has a high transmittance from ultraviolet to mid-infrared (250nm~7um), so it is widely used in the manufacture of prisms, Windows and lenses,
In some applications with a wide spectrum range, it can be used directly without coating film, Especially, it has low absorption and high laser threshold, so it is
suitable for application in excimer laser optical system, we are manufacture CaF2 optics, the size range from 3mm to 280mm, Surface Quality: 40-20,
Flatness:1/10 lambda@633nm(Lens diameter and thickness need to be right proportion)
