To minimize spherical aberration, when a plano-convex lens is used for focusing a collimated beam, the beam should be incident on the curved surface; when collimating a point source, the beam should be incident on the flat surface. The CaF₂ plano-convex lenses from LBTEK are coated with 2.0–5.0 μm AR coating on both surface to reduce the reflectivity of the lens. LBTEK utilizes CaF₂ for manufacturing various lenses due to its exceptional transmission across ultraviolet and infrared spectra, combined with high laser damage threshold, making it particularly suitable for excimer laser applications. With a relatively low refractive index ranging between 1.35 and 1.51 over the 180 nm to 8.0 µm spectral range, CaF₂ demonstrates superior chemical inertness compared to similar materials like BaF₂ and MgF₂.
