Design of miniaturization and super wide angle monitor lens based on monocentric lens
In order to meet the requirement of miniaturization, high image quality and large field of view of monitor lens, based on the monocentric structure lens and the development of curved sensor, a curved surface image monitoring lens optical system was designed. The FOV of the monitoring optical system is 140°, the focal length is 7.88 mm, the F-number is 1.5, the total length is 15.12 mm, and the monitoring lens is up to 11-megapixel. The final design shows that the MTF value is closed to the diffraction limit in the central field of view and the 0.7 field of view, and is greater than 0.59 at the full field of view. The RMS radius of all fields of view are less than 0.6 μm. Compared with the existing monitoring lens optical system, this design achieves excellent image quality in a large field of view with a miniaturization structure.super wide angle
