Large-size calcium fluoride crystal
Introduction to large calcium fluoride crystals: Large-size CaF₂ crystals are ultralarge-aperture optical materials made by special processes to produce high-performance components with exceptional clear-aperture requirements. Ultrapure purification, large-crystal growth control, stress-relief annealing and large-aperture polishing/inspection present costly technical barriers. Production capability represents leading national expertise in advanced optical materials. These crystals are strategic materials for semiconductors, astronomy and defense.
