Cylindrical lenses are mainly used in imaging systems, high-precision test instruments, and laser technology. AT OPtical, it can provide flat convex cylinder, flat concave cylinder, double convex cylinder, double concave cylinder, etc.
Spherical lenses have spherical surfaces for converging or diverging light, commonly used in glasses and microscopes.
Cylindrical lenses have curvature in one direction, used for beam shaping, often in laser applications.
At Optical make widely types of cylindrical lenses according to the material of BK7, H-K9L, fused silica, Silicon and so on.
High precision tester and high power laser: used for linear focusing and shaping of laser beam. long distance line interferometer for collimating and focusing beams.
Linear detector illumination: illumination for linear detectors.
Barcode scanning: for clear scanning of barcodes.
Holographic lighting: used for the production and lighting of holograms.
Computer and laser emission for computer display and laser emission systems. High intensity laser systems and synchrotron radiation beamlines for collimation and focusing of high brightness sources. Medical imaging for the focusing and imaging of X-rays and ultrasonics
Plano convex cylindrical lens: Consisting of a plane and a convex cylindrical lens capable of focusing incident rays onto a line. It is often used to focus parallel or divergent beams onto a line or to alter the aspect ratio of an image 12.
Plano-concave cylindrical lens consisting of one plane and one concave cylinder with a negative focal length, commonly used in applications of divergent beams 12.
Double convex and double concave cylindrical lenses: Used in different optical systems, double convex for spreading light and double concave for focusing light 2.
Cylindrical meniscus lenses: Having a special shape for use in specific optical design requirements.
The processing of optical cylindrical lenses includes rough grinding, fine grinding, and polishing. For rough grinding, small-radius lenses are processed using cylindrical or centerless grinders, while larger curvature lenses are shaped by milling. Fine grinding for small-radius lenses can be manual or batch-produced, medium-radius lenses are glued to molds for fine grinding, and concave or large-radius lenses are ground on specialized machines. Polishing is similar to fine grinding, using polishing molds with felt layers.
