Plano Concave Cylindrical Lens
Plano Concave Cylindrical Lenses are precision optical components with one flat surface and one cylindrical concave surface, designed to provide negative focal length and control light divergence along a single axis. Unlike spherical lenses that affect light in two dimensions, cylindrical lenses provide one-dimensional beam expansion or focusing. Chenyu Optics manufactures plano concave cylindrical lenses in BK7, fused silica and UV fused silica, uncoated or with UV AR, VIS AR and NIR AR coatings.
Plano Concave Cylindrical Lens Overview
Plano Concave Cylindrical Lenses are precision optical components with one flat surface and one cylindrical concave surface, designed to provide negative focal length and control light divergence along a single axis.
Unlike spherical lenses that affect light in two dimensions, cylindrical lenses provide one-dimensional beam expansion or focusing. They are widely used in laser beam shaping, line generation, optical scanning, imaging systems and machine vision applications.
Chenyu Optics supports custom plano concave cylindrical lens manufacturing according to customer drawings, including custom diameter, focal length, cylindrical radius and coating design for prototype and repeat production.
