Lens assembly

Abstract

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