The length of the contour curve of any surface of a single lens within the height range of 1/2 entrance pupil diameter (HEP) particularly affects the ability of the surface to correct aberrations in the common area of each ray field of view and the optical path difference between the fields of light. The longer the length of the contour curve, the better the ability to correct aberrations, but it will also increase. To increase the difficulty in manufacturing, it is necessary to control the length of the profile curve of any surface of a single lens within the height range of 1/2 incident pupil diameter (HEP), especially to control the 1/2 incident pupil diameter (HEP) of the surface. The proportional relationship between the length of the contour curve (ARE) in the height range and the thickness (TP) on the optical axis of the lens to which the surface belongs (ARE / TP). For example, the length of the contour curve of the 1/2 entrance pupil diameter (HEP) height of the side of the first lens is represented by ARE11. The thickness of the first lens on the optical axis is TP1. The ratio between the two is ARE11 / TP1. The length of the profile curve of the 1/2 entrance pupil diameter (HEP) height on the side of the mirror is represented by ARE12, and the ratio between it and TP1 is ARE12 / TP1. The length of the profile curve of the 1/2 entrance pupil diameter (HEP) height of the second lens object side is represented by ARE21, the thickness of the second lens on the optical axis is TP2, and the ratio between the two is ARE21 / TP2. The profile curve length of the 1/2 entrance pupil diameter (HEP) height on the side is represented by ARE22, and the ratio between it and TP2 is ARE22 / TP2. The proportional relationship between the length of the contour curve of the 1/2 entrance pupil diameter (HEP) height of any of the surfaces of the remaining lenses in the optical imaging module and the thickness (TP) of the lens on the optical axis to which the surface belongs, and its expression And so on.
