Abstract:
An optical imaging lens set includes a first lens element to a plastic fifth lens element from an object side toward an image side along an optical axis. Each first lens and second lens element has positive refractive power. The third lens element has an image-side surface with a convex portion in a vicinity of the optical axis. The fourth lens element has an image-side surface with a convex portion in a vicinity of the optical axis. The fifth lens element has an image-side surface with a concave portion in a vicinity of the optical axis and a convex portion in a vicinity of its periphery.
