Abstract

The present disclosure discloses an imaging lens assembly. Sequentially from an object side to an image side along an optical axis, the imaging lens assembly includes a first lens having a positive refractive power; a second lens having a negative refractive power, and both an object-side surface and an image-side surface thereof being concave surfaces; a third lens having a positive refractive power, and an image-side surface thereof being a convex surface; a fourth lens having a negative refractive power, and an object-side surface thereof being a concave surface; a fifth lens having a refractive power; and a sixth lens having a refractive power. A total effective focal length f of the imaging lens assembly and half of a diagonal length ImgH of an effective pixel area on an imaging plane of the imaging lens assembly satisfy 2.0≤f/ImgH≤3.0.
