Abstract

An image forming lens module is provided. The image forming lens module along an axial line from an object side to an image side includes in sequence a first lens, which is a biconvex lens having positive refracting power and at least one aspheric surface. A second lens, which is a meniscus lens having negative refracting power and at least one aspheric surface, wherein the second lens has a convex surface directed toward the object side. A third lens, which is a meniscus lens having positive refracting power and at least one aspheric surface, wherein the third lens has a concave surface directed toward the object side. A fourth lens, which is a lens having negative refracting power and at least one aspheric surface, wherein the refracting power of the fourth lens is negative turning into positive from the center to the edge.
