Abstract
A lens module includes a lens barrel, a first lens, an opaque plate, and a second lens. The first lens includes an imaging portion and a non-imaging portion surrounding the imaging portion. The non-imaging portion defines an annular conic surface. The opaque plate is annular conic shaped and contacts with the annular conic surface. The second lens includes an imaging portion and a non-imaging portion surrounding the imaging portion. The object-side surface of the non-imaging portion of the second lens is step-like shaped and includes at least two step surfaces. A junction of two adjacent step surfaces abuts against the opaque plate.
