Abstract
An optical imaging lens includes a first lens element, a second lens element, a third lens element, a fourth lens element, and a fifth lens element sequentially arranged along an optical axis from an object side to an image side. Each of the first lens element to the fifth lens element has an object-side surface facing toward the object side and an image-side surface facing toward the image side. A distance between the image-side surface of the fifth lens element and an image plane along the optical axis is BFL, an air gap between the first lens element and the second lens element along the optical axis is G12, an air gap between the fourth lens element and the fifth lens element along the optical axis is G45, a central thickness of the fifth lens element along the optical axis is T5, satisfying the equation: 1.861≤(BFL+G12)/(G45+T5)≤3.055.
