Plano Concave and Bi-Convex/concave Cylindrical Lens
Plano-concave Cylindrical Lens is an optical product, which is a divergent linear virtual image used to control the size of the light beam in only one direction. Combined with a plano-convex cylindrical lens, it can be used to shape the elliptical beam of a semiconductor laser into a circular beam. Plano-concave cylindrical mirrors can be used in projection systems, imaging systems, optical instruments, and laser measurement systems. Plano-concave cylindrical mirrors are also commonly used to convert a collimated laser source into a line light source, and plano-concave cylindrical mirrors are often used for beam expansion applications. Compared with spherical lenses, cylindrical lenses are more difficult to manufacture.Cylindrical lens is mainly used to change the design requirements of imaging size. For example, convert a point spot into a line spot, or change the height of the image without changing the desired width. The special optical performance of cylindrical mirrors. With the rapid development of high technology, cylindrical mirrors have become more and more widely used.
