Plano Convex Cylindrical Lens
Plano Convex Cylindrical Lenses are precision lenses with one flat surface and one cylindrically curved convex surface, focusing light to a line along a single axis rather than to a point. Chenyu Optics manufactures plano convex cylindrical lenses in BK7, fused silica, optical glass and infrared materials, with custom focal length, dimensions, surface quality and coating according to customer drawings.
Plano Convex Cylindrical Lens Overview
Plano Convex Cylindrical Lenses are precision lenses with one flat surface and one cylindrically curved convex surface, focusing light to a line along a single axis rather than to a point.
Compared with spherical or aspheric lenses, which focus light symmetrically in both axes, a cylindrical lens acts on only one axis while leaving the perpendicular axis unaffected, making it suitable for beam shaping, line generation and anamorphic imaging applications.
Chenyu Optics supports custom plano convex cylindrical lens manufacturing according to customer drawings, including custom material, focal length, dimensions, surface quality and coating for prototype and repeat production.
Key Advantages of Plano Convex Cylindrical Lens
Beam Shaping, Line Generation & Laser Systems
Plano convex cylindrical lenses are widely used in laser systems, beam shaping assemblies, line generation optics, machine vision systems and scientific instruments requiring single-axis focusing performance.
