Abstract
The present invention provides an optical imaging lens. The optical imaging lens comprises seven lens elements positioned in an order from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements, the optical imaging lens may shorten system length, enlarge aperture size and promote image height.
