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. The object-side surface of the fourth lens element has a convex portion in a vicinity of a periphery of the fourth lens element. The fifth lens element has negative refractive power. The effective focal length of the optical imaging lens EFL and the sum of all air gaps from the first lens element to the sixth lens element along the optical axis AAG of the optical imaging lens satisfies the relation: 0.9≤EFL/AAG≤2.6.
