Overview of calcium fluoride window sheets Calcium fluoride (CaF2) is a common optical material with high transparency and chemical stability. Due to its low spontaneous luminescence, radiation resistance, and biocompatibility, it is widely used in medical, scientific research, and other fields. Among them, calcium fluoride window sheets are a key material, mainly used in fields such as X-ray fluoroscopy, radiation therapy, and nuclear medicine imaging.
