Cross Cylindrical Lens
Cross Cylindrical Lenses are precision optical components designed for two-dimensional beam shaping, line generation and optical focusing applications in laser systems, imaging systems and machine vision equipment. By combining two cylindrical optical surfaces with perpendicular axes, these lenses provide independent control of light distribution in two orthogonal directions. Chenyu Optics manufactures cross cylindrical lenses in optical glass, fused silica and custom optical materials, uncoated or with AR, broadband AR, UV AR and NIR AR coatings.
Cross Cylindrical Lens Overview
Cross Cylindrical Lenses are precision optical components designed for two-dimensional beam shaping, line generation and optical focusing applications in laser systems, imaging systems and machine vision equipment.
By combining two cylindrical optical surfaces with perpendicular axes, cross cylindrical lenses provide independent control of light distribution in two orthogonal directions, enabling precise beam expansion, shaping and illumination control. They are widely used in laser line generation systems, machine vision lighting, optical measurement equipment and scientific optical instruments where accurate beam shaping is required.
Chenyu Optics supports custom cross cylindrical lens manufacturing according to customer drawings, including custom focal length, cylindrical axis orientation, dimensions and coating design for prototype and repeat production.
