An optical lens includes a first lens group and a second lens group arranged in order from a first side to a second side, and an aperture stop disposed between the first lens group and the second lens group. The optical lens satisfies the condition of LT/IMH<4.7, where IMH is semi-diagonal image height on an image plane, and LT is a distance along an optical axis between a surface of a first lens of the first lens group facing the first side and a surface of a last lens of the second lens group facing the second side. The first lens is closest to the first side among the first lens group, and the last lens is closest to the second side among the second lens group.
