Large Size Calcium Fluoride

Large size calcium fluoride refers to the research and development or batch demand of calcium fluoride with polycrystalline materials exceeding 150 millimeters and single crystals exceeding 120 millimeters. These products have high transparency, strength, heat resistance, and chemical stability, and are commonly used in astronomical observation, high-altitude imaging, satellite communication, public safety, and high-energy laser transmission. There are requirements for the stress and uniformity of the material itself, as well as for the precision of material processing. It is often recommended to use CNC or DTM for processing. If it involves opening holes and special shapes, it is recommended to provide requirements for material stress. It can process shapes such as circular, rectangular, perforated, crescent, wedge-shaped, flat convex, flat concave, double convex, double concave, open ball, and prismatic.
