A new method improving the design of panoramic lens with a long focal length based on ogive and aspheric surface is proposed. In this design, we use a special conjugation between "annular entrance pupil" and aperture stop to correct the chromatic transverse aberrations. Moreover, we use a new imaging relationship to increase the Effective Focal Length (EFL) of the panoramic lens and the CCD utilization. We realize a panoramic lens with a 360° × (45°~85°)field of view (FOV) and a 10.375mm EFL, which is 1.54 times than the conventional imaging relationship.
