Abstract
An optical imaging lens includes first, second, third, fourth and fifth lens elements positioned sequentially from an object side to an image side. The first lens element with positive refractive power has an object-side surface comprising a convex portion in the optical axis vicinity. The second lens element with negative refractive power has an object-side surface comprising a convex portion in the optical axis vicinity and an image-side surface comprising a concave portion in the optical axis vicinity. The third lens element has an image-side surface comprising a convex portion in the periphery. The fourth lens element has an image-side surface comprising a convex portion in the optical axis vicinity. The fifth lens element has an object-side surface comprising a convex portion in the optical axis vicinity and an image-side surface comprising a concave portion in the optical axis vicinity and a convex portion in the periphery.
