In order to achieve the miniaturization design of visible/short-wave infrared lenses, referring to the optical system with annular multireflection structure, and aiming at the problem that it is difficult to correct chromatic aberration in a single piece multireflection system, a compact dual piece annular multireflection optical lens with 1.3 million pixels is designed. The optimal obscuration ratio and optical parameters of the system are determined by analyzing their effect on the optical transfer function of the system. The optimized optical lens comprises two lenses made of calcium fluoride, which realize four reflections. Each reflective surface is an even aspheric surface. The proposed lens has a working band of 400?1700 nm, focal length of 75 mm, diameter of 50 mm, obscuration ratio of 0.75, and full field angle of 6.2°. The total length of the system is 22.7 mm, and the system length-to-focus ratio is 0.302. The optical transfer function curve of the proposed lens is smooth, more than 0.35 at 100 lp/mm, and its lateral color is <0.9 μm. The imaging quality of the proposed lens is good.
