Abstract
An optical imaging lens includes first, second, third, fourth, fifth and sixth lens elements arranged in order from the object side to the image side along an optical axis. The first lens element has negative refractive power. The object-side surface of the fourth lens element has a convex part in a vicinity of a periphery of the fourth lens element. The image-side surface of the sixth lens element has a convex part in a vicinity of a periphery of the sixth lens element. The effective focal length of the optical imaging lens is EFL, and a sum of all air gaps from the first lens element to the sixth lens element along the optical axis is AAG, and EFL and AAG satisfy 0.9≤EFL/AAG≤2.6.
