K9 Biconvex cylindrical lens

  • Biconvex 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 image width. It can be used in linear detector lighting, bar code scanning, holographic lighting, optical information processing, computer and laser emission. 

  • Optical cylindrical lenses is also widely used in high-power laser system and synchrotron radiation beam line. At the same time, the requirements for biconvex cylindrical mirror parts are becoming higher and higher, especially in high-precision testing instruments and devices such as cavity plate of high-power laser resonator and long-distance off-line interferometer.
