Abstract
A five-piece wide-angle lens module includes a first lens, a second lens, a third lens, a stop, a fourth lens and a fifth lens, which are sequentially arranged from an object side to an image side. The first lens has a negative refractive power, a convex surface on the object side, and a concave surface on the image side. The second lens has a negative refractive power and two concave surfaces on both sides. The third lens has a positive refractive power. The fourth lens has a positive refractive power and two convex surfaces on both sides. The fifth lens has a negative refractive power. Thereby, the five-piece wide-angle lens module can provide good image quality even in the environment with severe temperature changes.
