Calcium Fluoride CaF2 Window High Thermal Expansion Coefficient

Product description:

Its surfaces can be coated by Aluminum or silver or gold. Mirrors with dielectric high reflective coatings are also available.

The CaF2 Window is made from Calcium Fluoride material, which has transparent range from 170-7800nm.The refractive index is 1.399 at 5000nm.It has little hygroscopic susceptibility and high thermal expansion coefficient.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.
