Full sphere annular large visual field moon edge optical imaging object lens

A full sphere annular large visual field moon edge optical imaging object lens belongs to the technical field of optical design and solves the defects of high manufacture and detection cost of parts and the whole machine of an optical system in the prior art, and the uncertain work stability in the space environment. A first planar mirror combination, a second planar mirror combination, an imaging lens combination, a diaphragm, a piece of detector protection glass, and a detector are coaxially arranged according to a light incident sequence. The second planar mirror combination is arranged in front of the first planar mirror combination and arranged in parallel. The first planar mirror combination includes eight planar mirrors which are circumferentially uniformly distributed around a Z axis. The second planar mirror combination includes eight planar mirrors which are circumferentially uniformly distributed around the Z axis. The planar mirrors in the two planar mirror combinations are corresponding to each o
