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 collimation and circularization of laser diode output beams using dual cylindrical lens assemblies. 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 manufacture various lenses using N-BK7, 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 users with high-quality lens products at reasonable prices.
