Optical imaging lens

Abstract

An optical imaging lens may include 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, an eighth lens element and a nineth lens element positioned in an order from an object side to an image side. Through designing concave and / or convex surfaces of the lens elements, the optical imaging lens may increase resolution, increase aperture stop and image height, and maintain well image quality.
