The design with aspheric elements in optical system can make the design flexible.The aspheric elements used in optical system can reduce the number of the optical elements and improve optical system performance.The reducing of elements makes optical system assembling simple and reliable,moreover,also make the overall system become smaller and lighter.The application and advantage of aspheric elements in optical-electrical instruments are discussed and introduced here.
