Abstract
An optical imaging lens, sequentially including a first, second, third, fourth, fifth, sixth, seventh, eighth, and ninth lens elements along an optical axis from an object side to an image side, is provided. Each of the first to ninth lens elements includes an object-side surface facing the object side and allowing imaging rays to pass through, and an image-side surface facing the image side and allowing the imaging rays to pass through. The first lens element has positive refracting power, and a periphery region of the image-side surface is concave. An optical axis region of the object-side surface of the second lens element is convex. An optical axis region of the image-side surface of the ninth lens element is concave. Lens elements of the optical imaging lens are only the nine lens elements, and the optical imaging lens satisfies the following conditional expressions: V1+V2≤80.000 and V3+V7≥50.000.
