Summary:An optical 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 with positive refractive power and includes a convex surface facing an image side. The second lens is with positive refractive power and includes a convex surface facing an object side and another convex surface facing the image side. The third lens is with positive refractive power and includes a convex surface facing the object side and a concave surface facing the image side. The fourth lens is with positive refractive power and includes a convex surface facing the object side. The fifth lens is with negative refractive power and includes a concave surface facing the object side. The sixth lens and the seventh lens are meniscus lenses with positive refractive power. 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
