Product Description
Cylindrical lenses are aspheric lenses that can effectively reduce spherical aberration and chromatic aberration. They are classified into plano-convex cylindrical lenses, plano-concave cylindrical lenses, bi-convex cylindrical lenses and bi-concave cylindrical lenses. They feature one-dimensional magnification, for example, converting a point spot into a line spot, or changing the image height without altering the width. They can be applied in linear detector illumination, barcode scanning, holographic lighting, optical information processing, computers and laser emission. Optical cylindrical lenses are also widely used in high-power laser systems and synchrotron radiation beamlines.
