Abstract: An optical imaging lens includes a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, a seventh lens element, and an eighth lens element from an object side to an image side in order along an optical axis. The first lens element to the eighth lens element each include an object-side surface facing the object side and an image-side surface facing the image side. Lens elements of the optical imaging lens are only the first, second, third, fourth, fifth, sixth, seventh and eighth lens elements. The periphery region of the image-side surface of the first lens element is concave. The optical axis region of the image-side surface of the seventh lens element is concave, and the periphery region of the image-side surface of the seventh lens element is convex.

Abstract: Present embodiments relate to an optical imaging lens. The optical imaging lens may include a first lens element, a second lens element, a third lens element, a fourth lens element, and a fifth lens element positioned sequentially from an object side to an image side. Through arrangement of convex or concave surfaces of the five lens elements, the length of the optical imaging lens may be shortened while providing improved optical characteristics and imaging quality.
