CaF2 Window

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 l

aser 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 [email protected](Lens diameter and thickness need to be right proportion)
