Optical CaF2 Calcium Fluoride Plano-Convex Lens
Description
A calcium fluoride (CaF2) plano-convex lens is an optical component featuring one flat (plano) surface and one outwardly curved (convex) surface. Renowned for its exceptional transmission across a broad spectral range—from ultraviolet (UV, ~180 nm) to infrared (IR, ~8 μm)—CaF2 is particularly valued in deep-UV and high-power laser applications. Its low refractive index and minimal chromatic dispersion reduce spherical and chromatic aberrations, enhancing imaging precision. This lens is ideal for laser focusing, spectroscopy, lithography , and thermal imaging systems. Additionally, CaF2 exhibits high laser damage thresholds, thermal stability, and resistance to environmental degradation, making it suitable for demanding industrial, scientific, and defense applications.
