Product Description

• Optical Material: N-BK7
• Working Wavelength: 400 nm-700 nm (AR Coating)
• Circular geometry, housed in mechanical mount
• Applications: Imaging, single-direction beam collimation, beam shaping

The plano-convex circular cylindrical lens has one flat surface and one cylindrical surface, with a positive focal length. Unlike spherical lenses, cylindrical lenses act on the beam in only one direction. Cylindrical lenses are generally used for beam shaping, with typical applications including collimation with double cylindrical lens assemblies and circularizing the output beam of laser diodes. To reduce spherical aberration, when using a plano-convex cylindrical lens 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 two types of anti-reflection coatings: 400 nm–700 nm and 700 nm–1100 nm. Our lenses are finely processed with strict quality control, ensuring that LBTEK provides users with high-quality lens products at reasonable prices.
