Abstract
The present invention provides a six-piece optical lens assembly, which includes, from the object side to the image side, a first lens having negative optical power, wherein the object side surface of the first lens is convex near the optical axis, and the image side surface of the first lens is concave near the optical axis; a second lens having negative optical power, wherein the object side surface of the second lens is convex near the optical axis, and the image side surface of the second lens is concave near the optical axis; a third lens having positive optical power, wherein the object side surface of the third lens is convex near the optical axis, and the image side surface of the third lens is convex near the optical axis; an aperture; a fourth lens having positive optical power, wherein the object side surface of the fourth lens is convex near the optical axis, and the image side surface of the fourth lens is convex near the optical axis; a fifth lens having negative optical power, wherein the object side surface of the fifth lens is concave near the optical axis, and the image side surface of the fifth lens is concave near the optical axis; and a sixth lens having positive optical power. The lens assembly can correct the phase aberration of the imaging lens assembly to improve the imaging quality of the imaging lens assembly.
