Abstract:
1. An optical imaging lens, comprising in order along an optical axis thereof from an object side to an image side: a first lens element with positive refractive power that is a meniscus aspherical lens having a convex surface on the object side; an aperture stop; a second lens element with negative refractive power that is a meniscus aspherical lens having a convex surface on the image side; and a third lens element with positive refractive power that is an aspherical lens whose center is on the optical axis, while on the lens center, a convex surface is on the object side and a concave surface is on the image side; from the center of the third lens element toward the edge thereof, the refractive power changes from positive power, through an inflection point, to negative power; wherein the optical imaging lens satisfies conditions of wherein f is effective focal length of the optical imaging lens, f
