The invention relates to a high-resolution large-view-field optical lens for an aerial camera, and belongs to the technical field of photoelectric instruments. Comprising window glass (1), an objective lens assembly, a reflector (12) and a CMOS detector. The objective lens assembly comprises a first lens (2), a second lens (3), a third lens (4), a fourth lens (5), a diaphragm (6), a fifth lens (7), a sixth lens (8), a seventh lens (9), an eighth lens (10) and a ninth lens (11) which are sequentially and coaxially arranged from front to back in the light path direction. The window glass (1) and the first lens (2) are coaxially arranged, and the window glass (1) is arranged in front of the first lens (2); and the reflector (12) is obliquely fixed on the optical axis at a certain angle and is arranged behind the ninth lens (11). The optical system has the advantages of being simple in design, large in field angle, high in resolution, small in size and high in reliability.
