Abstract
An imaging optical system includes, in order from the object side to the image side, a first lens element, a second lens element, a third lens element, an aperture stop, a fourth lens element, a fifth lens element, and a sixth lens element arranged along an optical axis. The first lens element has a concave image-side surface in the vicinity of the optical axis. The second lens element has a negative refractive power. The third lens element has a convex object-side surface in a vicinity of an optical axis. The fourth lens element has a convex object-side surface in the vicinity of the optical axis. The fifth lens element has a convex image-side surface in the vicinity of the optical axis. The sixth lens element is made of plastic and has a convex image-side surface in a vicinity of an outer circumference.
