Abstract

An optical imaging lens, including a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, and a seventh lens element arranged in sequence from an object side to an image side along an optical axis, is provided. Each of the first lens element to the seventh lens element includes 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 object-side surface of the second lens element is concave and an optical axis region of the image-side surface of the second lens element is convex. The seventh lens element has negative refracting power and an optical axis region of the image-side surface of the seventh lens element is concave.
