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, and an eighth lens element positioned in an order from an object side to an image side along an optical axis. Through designing concave and/or convex surface of the lens elements, the optical imaging lens may have improved imaging quality, reduced system length, enlarged aperture stop, broad field of view and increased image height.
