Abstract
The present disclosure discloses an optical imaging lens group including, sequentially from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, each of which has refractive power. An object-side surface of the first lens is a convex surface, and an image-side surface of the first lens is a concave surface; an image-side surface of the second lens is a concave surface; and an object-side surface of sixth lens is a concave surface. A distance TTL along the optical axis from an object-side surface of the first lens to an imaging plane of the optical imaging lens group and half of a diagonal length ImgH of an effective pixel area on the imaging plane of the optical imaging lens group satisfy TTL/ImgH≤1.23.
