Abstract
An optical imaging lens includes a first lens element to a ninth lens element, and each lens element has an object-side surface and an image-side surface. A periphery region of the image-side surface of the first lens element is concave, the second lens element has negative refracting power, the eighth lens element has negative refracting power, and an optical axis region of the object-side surface of the ninth lens element is concave. Lens elements included by the optical imaging lens are only the nine lens elements described above, and the optical imaging lens satisfies the distance from the object-side surface of the first lens element to an image plane on the optical axis is less than or equal to 15.000 mm.
