产品特点

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. 

1.Useful transmission over the spectral range from 0.2 to 8.0 microns..

2.Low solubility 3.Because of its composition CaF₂ window has a much longer useful life than most other materials when use in a fluorine environment. 

4.We have two grades of material of CaF₂ window. One is for UV application, the other is for IR application. A wide transmission range and low solubility makes it useful for many application, including:

> Mirror substrate for UV laser systems 

> Substrate for manufacturing Windows, Lenses for UV and IR application
