Abstract: 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.

Abstract: Present embodiments provide for a mobile device and an optical imaging lens thereof. The optical imaging lens comprises an aperture stop and six lens elements positioned sequentially from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least one inequality, the optical imaging lens shows better optical characteristics and the total length of the optical imaging lens is shortened.
