Abstract
A new method using cemented lenses to improve the design of Panoramic Annular Lens (PAL) is introduced. This structure can help to realize the design of PAL optical system with long focal length, which can help to see much further than the ones with short focal lengths. It can also keep the volume of the system moderate. The chromatic aberration of PAL is investigated theoretically. Method of selecting proper cemented glasses of PAL is also discussed. A doublet PAL and its relay optics with a total effective focal length of 10.3mm are realized.
