Abstract

The present disclosure discloses an optical imaging lens assembly, which includes sequentially from an object side to an image side along an optical axis, a first lens and at least one subsequent lens having refractive power. A distance TTL along the optical axis from an object-side surface of the first lens to an image plane of the optical imaging lens assembly and a distance P along the optical axis from a to-be-captured object to the object-side surface of the first lens satisfy 0.6<TTL/P*10<1.8.

Claims (20)

where TTL is a distance along the optical axis from an object-side surface of the first lens to an image plane of the optical imaging lens assembly, and P is a distance along the optical axis from a to-be-captured object to the object-side surface of the first lens;

0.55<| f/R 1|<2.6,

where f is a total effective focal length of the optical imaging lens assembly, and R 1 is a radius of curvature of the object-side surface of the first lens; and

0.3< DT 12/ DT 11<1.6,

where DT 12 is an effective aperture radius of an image-side surface of the first lens, and DT 11 is an effective aperture radius of the object-side surface of the first lens.

2. The optical imaging lens assembly according to claim 1 , wherein among the first lens and the at least one subsequent lens, an object-side surface of a lens closest to the image plane of the optical imaging lens assembly is a convex surface.

3. The optical imaging lens assembly according to claim 2 , wherein among the first lens and the at least one subsequent lens, |RLS 2 /RLS 1 |≤2.0,

where RLS 2 is a radius of curvature of an image-side surface of the lens closest to the image plane of the optical imaging lens assembly, and RLS 1 is a radius of curvature of the object-side surface of the lens closest to the image plane of the optical imaging lens assembly.

4. The optical imaging lens assembly according to claim 2 , wherein the at least one subsequent lens includes a second lens, and an object-side surface of the second lens is a convex surface.

5. The optical imaging lens assembly according to claim 2 , wherein the at least one subsequent lens, sequentially from the object side to the image side along the optical axis, includes a second lens, a third lens and a fourth lens, and an object-side surface of the fourth lens is a convex surface.
