Abstract

The present disclosure discloses an optical imaging lens assembly including, sequentially from an object side to an image side along an optical axis, a first lens having positive refractive power with a convex object-side surface and a concave image-side surface; a second lens having negative refractive power with a concave image-side surface; a third lens having refractive power with a convex object-side surface and a concave image-side surface; a fourth lens having refractive power; a fifth lens having refractive power; a sixth lens having refractive power; a seventh lens having positive refractive power with a convex object-side surface; and an eighth lens having negative refractive power with a concave object-side surface and a concave image-side surface, wherein half of a diagonal length ImgH of an effective pixel area on an imaging plane of the optical imaging lens assembly satisfies: 5.80 mm<ImgH.
