Abstract
The present invention provides an optical imaging lens. The optical imaging lens comprises nine 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 be provided with reduced f number and increased image height, along with good imaging quality.
