Patent attributes
The present disclosure discloses an optical imaging lens assembly. The optical imaging lens assembly includes: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens in sequence from an object side to an image side along an optical axis. The first lens, the second lens, and the sixth lens each have a positive refractive power. The third lens and the seventh lens each have a negative refractive power. The fourth lens and the fifth lens each have a refractive power. Object-side surfaces of the first lens and the second lens are both convex surfaces. An image-side surface of the third lens is a concave surface. A total effective focal length f of the optical imaging lens assembly and a radius of curvature R13 of an object-side surface of the seventh lens satisfy: |f/R13|≥2.5.
