Abstract:
A compact low-profile low-cost imaging lens with a small F-value which offers a wide field of view and corrects aberrations properly. Its elements are spaced from each other and arranged from an object side to an image side as follows: a first positive lens having a convex object-side surface; a second negative lens; a third positive or negative lens; a fourth positive or negative lens; a fifth positive or negative lens; a sixth positive or negative lens; and a seventh lens as a double-sided aspheric lens having a concave image-side surface. The third to sixth lenses each have at least one aspheric surface. The aspheric image-side surface of the seventh lens has a pole-change point off an optical axis. The imaging lens satisfies a conditional expression −1.0<f1/f2<−0.15, where f1 denotes focal length of the first lens, and f2 denotes focal length of the second lens.

Claim (Index 21):
An imaging lens configured to form an image of an object on a solid-state image sensor, in which the lenses are arranged in order from an object side to an image side of the imaging lens and are spaced from each other, the imaging lens comprising:\n a first lens with a positive refractive power; a second lens with a negative refractive power; a third lens with a positive or a negative refractive power; a fourth lens with a positive or a negative refractive power; a fifth lens with a positive refractive power having a concave surface facing the object side near an optical axis and a convex surface facing the image side near the optical axis; a sixth lens with a positive or a negative refractive power; and a seventh lens with a negative refractive power, the seventh lens being a double-sided aspheric lens having a concave surface facing the object side near the optical axis and a concave surface facing the image side near the optical axis, wherein the third lens, the fourth lens, the fifth lens, and the sixth lens each have at least one aspheric surface, the seventh lens has a pole-change point spaced from an optical axis of the imaging lens on its aspheric image-side surface, and an expression (6) is satisfied:\n 20 <vd 1 \u2212vd 2<40, where \u2003\u2003(6) \n vd1: abbe number of the first lens at d-ray, and vd2: abbe number of the second lens at d-ray.
