Abstract

The present disclosure provides 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; a second lens having positive refractive power and a convex object-side surface; and a third lens having negative refractive power. 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 assembly and half of a diagonal length ImgH of an effective pixel area on the imaging plane satisfy 2.0<TTL/ImgH<2.5.
