IR Grade Calcium Fluoride Sheet

IR Grade Calcium Fluoride Sheet provides wide-band optical transmission, excellent resistance to moisture, and mechanical stability in a planar form optimized for large-area infrared applications. With transmission from 150 nm to 9 μm, it is widely used in optics, laser systems, and thermal imaging. Industries such as aerospace, defense, and photonics employ calcium fluoride sheets for IR windows, laser substrates, and protective covers. Specific applications include protective shields in spectroscopy systems, optical substrates for thin-film coatings, and IR-transparent components in cryogenic systems. Research investigates their role in radiation damage studies, nonlinear optical applications, and advanced IR laser optics. The sheet form allows machining into custom geometries, scalability for large-area optics, and uniform optical response, reinforcing its importance in both industrial laser systems and high-precision infrared scientific instrumentation.
