Abstract:
1. An optical 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 object-side surface in a paraxial region; a second lens element having negative refractive power; a third lens element having refractive power; a fourth lens element with negative refractive power having a concave object-side surface in a paraxial region; a fifth lens element with positive refractive power having a convex image-side surface in a paraxial region, wherein both of an object-side surface and the image-side surface of the fifth lens element are aspheric; and a sixth lens element with negative refractive power having a concave object-side surface in a paraxial region, a concave image-side surface in a paraxial region and at least one convex shape in an off-axial region of the image-side surface of the sixth lens element, wherein both of the object-side surface and the image-side surface of the sixth lens element are aspheric; wherein the optical imaging lens assembly has a total of six lens elements with refractive power, a curvature radius of the object-side surface of the fourth lens element is R7, a curvature radius of the image-side surface of the fifth lens element is R10, a curvature radius of the object-side surface of the sixth lens element is R11, a curvature radius of the image-side surface of the sixth lens element is R12, a focal length of the optical imaging lens assembly is f, and the following relationships are satisfied:
