Abstract
An optical imaging lens includes a first lens element to a sixth lens element from an object side to an image side along an optical axis. An optical axis region of the object-side surface of the first lens element is concave, a periphery region of the object-side surface of the second lens element is convex, 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 sixth lens element is convex. Lens elements included by the optical imaging lens are only six lens elements described above. ImgH is an image height of the optical imaging lens and AAG is a sum of five air gaps from the first lens element to the sixth lens element along the optical axis to satisfy ImgH/AAG≥3.200.
