Infrared Calcium Fluoride(IR Caf2)

IR Calcium Fluoride

Infrared calcium fluoride(IR Caf2) is a colorless crystalline material with high transmittance to infrared radiation. With a transmittance of more than 80% and a good light transmittance between 0.125 and 9μm, it is an ideal material for making various optical components such as optical Windows, prisms and lenses. It is used in optical instrument, infrared laser, optical coating and other fields. Micron optics as an optical crystal manufacturer can process the shape of round, rectangular, open hole, meniscus, wedge Angle, flat convex, flat concave, double convex, double concave, open ball, prism.
