Claim 0:
1. An optical imaging lens comprising a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element sequentially from an object side to an image side along an optical axis, the first lens element to the seventh lens element each comprising an object-side surface facing toward the object side and allowing imaging rays to pass through and an image-side surface facing toward the image side and allowing the imaging rays to pass through, wherein:
the object-side surface of the fourth lens element comprises a concave portion in a vicinity of a periphery of the fourth lens element;
the object-side surface of the fifth lens element comprises a convex portion in a vicinity of the optical axis and a convex portion in a vicinity of a periphery of the fifth lens element;
the object-side surface of the sixth lens element comprises a concave portion in a vicinity of a periphery of the sixth lens element; and
lens elements included by the optical imaging lens are only the seven lens elements described above;
wherein a distance from the object-side surface of the first lens element to an image plane along the optical axis is represented by TTL, an image height of the optical imaging lens is represented by ImgH, a sum of the thicknesses of the first lens element, the second element, the third element, the fourth element, the fifth element, the sixth element, and the seventh lens element along the optical axis is represented by ALT, a F-number of the optical imaging lens is represented by Fno, a thickness of the third lens element along the optical axis is represented by T3, a distance between the third lens element and the fourth lens element along the optical axis is represented by G34, and the optical imaging lens further satisfies inequalities: TTL/ImgH≤2.300, and ALT*Fno/(T3+G34)≤8.800.
