Abstract
An optical imaging lens includes a first lens element to a fifth lens element from an object side to an image side in order along an optical axis, and each lens element has an object-side surface and an image-side surface. An optical axis region of the image-side surface of the first lens element is concave, a periphery region of the image-side surface of the fourth lens element is concave, an optical axis region of the object-side surface of the fifth lens element is convex, and a periphery region of the image-side surface of the fifth lens element is convex. EFL is an effective focal length of the optical imaging lens and TTL is a distance from the object-side surface of the first lens element to an image plane along the optical axis to satisfy 1.1≤EFL/TTL≤1.6.
