The fifth lens is with refractive power. The sixth lens is with refractive power.

Abstract: A wide-angle lens comprises sequentially from an object side to an image side along an optical axis a first lens, a second lens, a stop and a third lens. The first lens is a biconcave lens and with negative refractive power. The second lens is a convex-concave lens with positive refractive power and includes a convex surface facing the object side and concave surface facing the image side. The third lens is with positive refractive power and includes a convex surface facing the image side. The wide-angle lens satisfies the following condition: 2.9<DL1DL2<3.1 wherein DL1 is an effective diameter of the first lens and DL2 is an effective diameter of the second lens.
