Description:
CaF2 is a cubic single crystal, It has good transmission from UV to middle infrared wavelength,
CaF2 material is relatively soft and somewhat hygroscopic, so polishing, coating and handling are more critical
than UV Fused Silica components.
Application:
1. It is always used in excimer laser components.
2. Beside UV application, CaF2 also is commonly used in IR components such as windows, Lenses and Prisms.
Properties:
Transmission range:170nm-7775nm
Thermal expansion coefficient:18.85*10-6/K
Density:.318g/cm3
