Abstract

In order to meet the requirement of miniaturization, high image quality and large field of view of monitor lens, based on the characteristics of monocentric lenses, and the development of curved image sensors, we designed a monitor lens optical system and all refraction surfaces and its curved image surface have the same spherical center. The monitoring optical system's FOV is 140°, the focal length is 7.88mm, the F-number is 1.50, and the total length is 14.47 mm. The monitoring optical system is up to 11-megapixel. The final design result 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 all fields of view. The RMS radiuses of different fields of view are all less than 1.1 μm . It can be clearly seen that the aberrations of each field of view are well controlled from the quantitative analysis of the transverse ray fan plot. The monitor lens has good performance in quite a large FOV with a miniaturization structure.
