Abstract:
1. An imaging lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex image-side surface; a second lens element having refractive power; a third lens element having refractive power; a fourth lens element having refractive power; a fifth lens element having negative refractive power; and a sixth lens element with negative refractive power having a concave image-side surface in a paraxial region thereof, wherein an object-side surface and the image-side surface of the sixth lens element are aspheric, and at least one of the object-side surface and the image-side surface of the sixth lens element has at least one inflection point; wherein the imaging lens assembly has a total of six lens elements with refractive power, a focal length of the imaging lens assembly is f, a curvature radius of the image-side surface of the first lens element is R2, a focal length of the sixth lens element is f6, and the following conditions are satisfied:
