| Material Properties |
|
CaF2 has excellent transmission in the UV, they are often used to make windows with high transmittance from below 150 nm and extending throughout the visible range. CaF2 Windows are relatively soft and somewhat hygroscopic so polishing, coating and handling are more critical than UV Fused Silica windows. In addition, The quality of a UV window can be extremely critical, it should be of high purity and polish in order not to affect the optical system.
Calcium Fluoride Windows are also applicable for a wide range of spectrum. It is particularly useful for wavelength at 2980nm laser application.
