Abstract

A wide-angle lens assembly includes a first, a second, a third, a fourth, a fifth, a sixth, a seventh, an eighth, a ninth, and a tenth lenses, all of which are arranged in order from an object side to an image side along an optical axis. The first lens is a meniscus lens with negative refractive power. The second lens is with refractive power. The third lens is with negative refractive power. The fourth, seventh, and ninth lenses are with positive refractive power. The fifth lens is a meniscus lens with refractive power and includes a concave surface facing the object side and a convex surface facing the image side. The sixth lens includes a convex surface facing the object side. The eighth lens includes a concave surface facing the image side. The tenth lens is with positive refractive power and includes a convex surface facing the object side.
