1．CaF2 (visible and infrared grades), 2．CaF2(ArF grade)
Main products（Optical Crystals, Scintillators and Radiation Detectors）
IoT / Electronics
Parts / materials
Calcium fluoride(CaF2), an optical material characterized by its low light dispersion, has a history of use in imaging applications that demand high quality. High definition television and other high resolution products represent a growing market for both visible and infrared grades of CaF2. The ArF grade, with its high transparency in the vacuum ultraviolet (VUV) region, is used as the primary optical component for excimer lasers and laser-based lithography equipment.
