Abstract

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