Product Description

• Optical Material: N-BK7
• Working Wavelength: 350 nm-2.0 µm (uncoated)
• Application: Imaging, unidirectional beam collimation, beam shaping

The plano-concave cylindrical lens has one flat surface and one cylindrical surface, featuring a negative 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 with dual cylindrical lens assemblies and circularizing the output beam of laser diodes. To reduce spherical aberration, plano-concave cylindrical lenses are used to diverge a collimated beam into a spot, and the beam should be incident on the curved surface of the lens. LBTEK chooses to manufacture various lenses using N-BK7, which is the most common lens material and widely used in visible and near-infrared applications. LBTEK offers uncoated plano-concave 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.
