Calcium Fluoride Plano-convex Cylindrical Lens

Calcium fluoride cylindrical lenses have high transmittance and a wide spectral range, with high transmittance in the ultraviolet, visible, and near-infrared spectral regions. It also has a lower refractive index and dispersion index, which can effectively correct chromatic aberration and reduce beam divergence. Applied in lasers, telescopes, microscopes, etc. Can be coated with reflective film, anti reflective film, filter film, spectroscopic film, polarizing film, and metallization film systems.
