Abstract
The optical imaging lens includes five lens elements from an object side to an image side. The optical imaging lens shows better optical characteristics through controlling the convex or concave shape of the surfaces of the lens elements to allow the thicknesses of the second and third lens elements and air gaps between the five lens elements along the optical axis satisfying the relations 1.715≤AAG/(AG45)≤7.593 and 2.124≤ALT/(T2+T3)≤3.937, where AAG is the sum of all four air gaps from the first to the fifth lens element along the optical axis, AG45 is an air gap between the fourth and fifth lens elements along the optical axis, ALT is the sum of thicknesses of the first to fifth lens elements along the optical axis, and T2 and T3 are the respective thickness of the second and third lens elements along the optical axis.
