Plano-Convex Cylindrical Lens, N-BK7, Uncoated: 350-2000 nm OLYC0201051
The plano-convex cylindrical lens offered by JCOPTIX is a type of aspheric lens that shapes the beam in one dimension to change the spot size. It uses a flat surface and a convex cylindrical surface and has a positive focal length. When light enters the lens, using the convex surface as the entrance surface effectively reduces spherical and chromatic aberration. N-BK7 is a common optical lens material with good consistency and high homogeneity, widely used in visible and near-infrared applications. The N-BK7 series of cylindrical lenses offered by JCOPTIX are all made of N-BK7 and can be used with high-power lasers, satellite technology and astronomical optical equipment. JCOPTIX offers optical lenses in different materials, including N-BK7 and UV fused silica. Lenses in these materials can be supplied without antireflection coatings for a wide operating wavelength range and a high damage threshold, or with optional antireflection coatings. JCOPTIX currently offers three antireflection coating wavelength bands for N-BK7 lenses: 350-700 nm, 650-1100 nm and 1050-1700 nm. JCOPTIX provides customization for different application scenarios and requirements, including lens dimensions, material, focal length and coating.
