The plano-convex cylindrical lens has one flat surface and one cylindrical surface, with a positive focal length. Unlike spherical lenses, cylindrical lenses only act on the beam in one direction. Cylindrical lenses are generally used for beam shaping, with typical applications including including collimation with dual cylindrical lens assemblies and circularizing the output beam of laser diodes. To reduce spherical aberration, when a plano-convex cylindrical lens is used to focus a collimated beam into a line, the beam should be incident on the curved surface of the lens; when collimating a line source, the beam should be incident on the flat surface of the lens. LBTEK chooses to use N-BK7 to manufacture various lenses, as N-BK7 is the most common lens material, widely used in visible and near-infrared applications. LBTEK offers uncoated plano-convex cylindrical lenses as well as lenses with three types of anti-reflection coatings: 400 nm-700 nm, 700 nm-1100 nm, and 1100 nm-1650 nm. Our lenses are finely processed with strict quality control, ensuring that LBTEK provides high-quality lens products to users at reasonable prices.
