Abstract: An imaging lens is provided. The imaging lens includes, in an order from an object side to an image plane side, a first lens having an object side surface that is convex and having a positive refractive power, a second lens having a positive or negative refractive power, a third lens having a positive or negative refractive power, a fourth lens having a negative refractive power, and a fifth lens having a positive or negative refractive power, wherein an image side surface of the fifth lens has a concave center portion and has at least one inflection point, and the imaging lens satisfies a condition that −0.25≦(Y−yp)/yp≦−0.05, where Y denotes an image height of a real chief ray, and yp denotes an image height of a paraxial chief ray.

Abstract: An imaging lens includes a first lens having a convex surface toward an object and positive refractive power, a second lens having positive or negative refractive power, a third lens having positive or negative refractive power, a fourth lens having a convex surface toward an image plane and positive refractive power, and a fifth lens having a concave surface toward an object and negative refractive power. The first through fifth lenses are arranged in order from an object to an image plane. The imaging lens satisfies the condition −0.2≦(Y−yp)/yp≦−0.05, wherein Y indicates an image height of a real chief ray, and yp indicates an image height of a paraxial chief ray.
