Cylindrical mirrors are commonly used to change the shape of light sources in optical systems, making them linear light sources. Cylindrical mirrors can be used for correcting astigmatism in the system. It is widely used in high-precision testing instruments and devices such as high-power lasers and long-distance offline interferometers. At the same time, cylindrical mirrors are also often used in Synchrotron radiation beam lines, bar code scanners and high power laser systems, Electron optics metrological verification, laser scanners, Spectroscopy, laser diode output light shaping and beauty, light sheet lighting lamp microscope imaging and other manufacturing industries and industries.
Optical cylindrical lenses focus incident light onto a line with a positive focal length, consisting of a plane and a convex cylindrical surface. They are commonly used to concentrate parallel or divergent light beams onto the line or change the aspect ratio of the image. A flat concave cylindrical lens is composed of a plane and a concave cylindrical surface, with a negative focal length. It is commonly used to concentrate parallel or divergent light beams onto a line or change the aspect ratio of the image, and has the function of transforming a point light source into a linear light source.
