Ultraviolet Calcium Fluoride(UV Caf2)

UV Calcium Fluoride

The ultraviolet calcium fluoride optical crystal(UV Caf2) band is 200-400nm, which is characterized by no obvious absorption at 205NM and 306NM, and requires that the pass-through rate of the infrared band will not be reduced. Ultraviolet single crystal is used in solar blind detector 260-280NM or ultraviolet imaging to play an achromatic role, so that the noise is lower and the image quality is better. At the same time, it is also used in the ultraviolet vacuum observation window or spectral analysis. It can be processed in the shape of round, rectangular, open hole, meniscus, wedge Angle, flat convex, flat concave, double convex, double concave, open ball, prism. UM OPTICS has complete optical crystal production equipment and experience, can provide you with high quality UV calcium fluoride optical crystals.
