Calcium Fluoride (CaF2) Windows & Plates

Calcium Fluoride (CaF2) is ideal for applications in the UV 200nm to IR 7μm. It has a high damage threshold and low absorption. It makes an excellent choice for FTIR analysis, excimer laser systems and often used as a spectroscopic window and in thermal imaging systems. AR coatings are applied for increased transmission for the IR or UV wavelengths and other specified orientations cut to <100> <110> <111>. Additional optical grades of Monocrystalline and Polycrystalline CaF2 are processed including VUV and Raman grades.

UQG optics Calcium Fluoride (CaF2) windows and plates are made as diameters and squares to a standard stock range or custom made to your design.
