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