Abstract:
An imaging lens includes a first lens group; a second lens group; and a third lens group. The first lens group includes a stop, a first lens having positive refractive power, a second lens, and a third lens. The second lens group includes a fourth lens and a fifth lens. The third lens group includes a sixth lens and a seventh lens. The first to seventh lenses are arranged on an optical axis with a space in between respectively. The fifth lens is formed in a meniscus shape near an optical axis thereof. The seventh lens is formed in a shape so that a surface thereof on the image plane side has a positive curvature radius. The surface of the seventh lens on the image plane side is formed in an aspheric shape having at least one inflexion point. The third lens has a specific Abbe's number.

Claim (Index 1):
An imaging lens comprising:\n a first lens group; a second lens group; and a third lens group, arranged in this order from an object side to an image plane side, wherein said first lens group includes a stop, a first lens having positive refractive power, a second lens, and a third lens, said second lens group includes a fourth lens and a fifth lens, said third lens group includes a sixth lens and a seventh lens, said first lens, said second lens, said third lens, said fourth lens, said fifth lens, said sixth lens, and said seventh lens are arranged on an optical axis with a space in between respectively, said fifth lens is formed in a meniscus shape near an optical axis thereof, said seventh lens is formed in a shape so that a surface thereof on the image plane side has a positive curvature radius, said surface of the seventh lens on the image plane side is formed in an aspheric shape having at least one inflexion point, and said third lens has an Abbe's number \u03bdd 3  so that the following conditional expression is satisfied:\n 20<\u03bdd3<35.
