1. An optical image capture apparatus, comprising:
a front lens group, comprising a first incident lens and a second incident lens, the second incident lens is located between the first incident lens and the incident surface, the first incident lens and the second incident lens are provided with the incident axis, the second incident lens is provided with the contact portion, and the contact portion is substantially in contact with the incident surface to enable the incident surface to be aligned with the incident axis;
an optical redirecting assembly, comprising an optical redirecting component, wherein the optical redirecting component is provided with an incident surface, a reflective surface, and an emergent surface, and the contact portion is substantially in contact with the incident surface, to enable the incident axis to pass through the incident surface, be reflected on the reflective surface, and pass through the emergent surface as an emergent axis;
a fixed lens group, substantially in contact with the emergent surface to enable the fixed lens group to be substantially aligned with the emergent axis, and comprising a first fixed lens and a second fixed lens;
a focusing lens module, comprising a focusing lens group and an actuator, wherein the focusing lens module is adjacent to the fixed lens group and the focusing lens group is substantially aligned with the emergent axis, and the actuator is configured to actuate the focusing lens group to move along the emergent axis;
the focusing lens group comprises a first focusing lens, and a second focusing lens; and
an image sensor, adjacent to the focusing lens module and substantially aligned with the emergent axis;
wherein the first incident lens, the second incident lens, the first fixed lens, the second fixed lens, the first focusing lens, and the second focusing lens each have a diopter, the diopter of the first incident lens is positive, the diopter of the second incident lens is positive, the diopter of the first fixed lens is negative, the diopter of the second fixed lens is negative, the diopter of the first focusing lens is positive, and the diopter of the second focusing lens is positive.
