MOBILE DEVICE AND OPTICAL IMAGING LENS THEREOF

摘要

An optical imaging lens comprises first, second, third, fourth, fifth and sixth lens elements arranged sequentially from an object side to an image side along an optical axis. Each of the lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The object-side surface of the first lens element has a convex portion in the vicinity of the optical axis. The third lens element has positive refracting power. The object-side surface of the third lens element has a concave portion in the vicinity of the optical axis. The object-side surface of the fourth lens element has a concave portion in the vicinity of the optical axis. The object-side surface of the fifth lens element has a concave portion in the vicinity of its periphery.
