Abstract
An imaging optical lens includes, in order from object side to image side, an aperture stop, first, second, third, fourth, and fifth lens elements, each of the five lens elements having an object side surface and an image side surface. The object side surface of the first lens element is convex along an optical axis. The image-side surface of the second lens element concave in the vicinity of an outer circumference. The object side of the fourth lens element is convex in the vicinity of the outer circumference. The image side surface of the fifth lens element is concave in the vicinity of the optical axis and convex in the vicinity of the outer circumference. The first, second, third, fourth, and fifth lens elements have a refractive power. The thicknesses of the first, second, third, fourth, and fifth lens elements and the air gaps between them satisfy specific conditions.
