1. Calcium fluoridecrystal (Coating material)
Application:Our products of optical crystal CaF2is quality optical materials applying to highprecision optical components such as windows, prisms,substrates, beam splitter, optical wedges, cylindtrical mirrors, nonspherical mirrors etc. It is the most important and main material in apochromatic lenseds system. The outstanding properties at UV band make it used in UV microlithography in electronic chips manufacture aspects. Because of the good properties at UV, Vis and IR band, CaF2
optical crystals are applied widely in sciences research , high-tech and civil industry.
