Calcium Fluoride is an optical grade glass which has an extensive transmision range from UV, visiable and IR spectrum. CaF2 has a high transmittance especially from 200nm to 7μm. The transmittance of uncoated caf2 window can up to 94% in visible range due to its low absorption and low index of refraction. CaF2 is widely used in UV and IR applications .

We offer high precision and quality caf2 windows with cost-benefit price as well as stable supply ability. Dimensions and shape depends on your project. Meanwhile, experienced engineer could advise you professional advices according to your applications, drawing is aslo available.
