Abstract

A lens module includes a lens barrel, a number of lenses, a number of opaque plates, and a filter glass. The barrel, the lenses, the opaque plates, and the filter glass all are received in the lens barrel. Each opaque plate is sandwiched between two adjacent lenses. Each lens includes an imaging portion and a non-imaging portion surrounding the imaging portion for engaging an inner sidewall of the lens barrel. The filter glass is arranged closer to an image-side of the lens module than the lens and the opaque plates. The projection of one of the opaque plates arranged closest to the filter glass, along the direction of incident light of the lens module, totally covers the non-imaging portion of the lens arranged closest to the filter glass.
