Description
Optical glass Calcium Fluoride windows and lens
An Optical Window is an optically flat. These regular windows are applied to isolate different physical environments while
allowing light pass. When selecting windows,please consider materials, transmission, scattering, parallelism and resistance to certain environment. It can be widely used on laser technology, IR detector and imaging technology etc.
Lianze Promise offers standard and high precision optical glass windows in round ,rectangular, wedge windows and custom shape and size with different optical glasses,Fused Silica, Sapphire, ZnSe, Zns and IR crystal. The high precision parallelism of 10 arc seconds, surface quality of 10/5 and flatness of λ/20. Single layer or multi-layer anti-reflection coatings are available.

Principle:
Calcium fluoride (CaF2) has a high transmittance between ultraviolet and mid-infrared (250nm~7um), so it is widely used in the manufacture of prisms, windows and lenses, etc.In particular, it has low absorption and high laser threshold.
Features:
The calcium fluoride (CaF2) lens or window produced by our company, the diameter range is: 3~500mm, the surface accuracy can usually reach 40/20, and the surface flatness can reach: λ/10@633nm (the ratio of the thickness of the lens to the diameter Need to meet the processing ratio).
Application:
It is suitable for excimer laser optical system.
