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; a second lens element with negative refractive power having a concave object-side surface; a third lens element with refractive power; a fourth lens element with refractive power; a fifth lens element with refractive power having a concave object-side surface and a convex image-side surface, wherein at least one of the object-side surface and the image-side surface of the fifth lens element is aspheric; and a sixth lens element with refractive power having a concave image-side surface, wherein an object-side surface and the image-side surface of the sixth lens element are aspheric, and the sixth lens element has at least one inflection point on the image-side surface thereof; wherein a curvature radius of the object-side surface of the second lens element is R3, a curvature radius of an image-side surface of the second lens element is R4, a focal length of the optical imaging lens assembly is f, a focal length of the fifth lens element is f5, and the following relationships are satisfied:
