Abstract:
An imaging lens includes a first lens group; a second lens group; and a third lens group, arranged in this order from an object side. The first lens group includes a first lens having positive refractive power, a second lens, and a third lens with a space in between. The second lens group includes a fourth lens having negative refractive power and a fifth lens with a space in between. The third lens group includes a sixth lens having negative refractive power and a seventh lens with a space in between. A surface of the second lens on the object side has a positive curvature radius. A surface of each of the third lens and the sixth lens on the image plane side has a positive curvature radius. A surface of the fourth lens on the object side has a negative curvature radius. The first 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 first lens having positive refractive power, a second lens, and a third lens, arranged respectively with a space in between, said second lens group includes a fourth lens having negative refractive power and a fifth lens, arranged respectively with a space in between, said third lens group includes a sixth lens having negative refractive power and a seventh lens, arranged respectively with a space in between, said second lens is formed in a shape so that a surface thereof on the object side has a positive curvature radius, said third lens is formed in a shape so that a surface thereof on the image plane side has a positive curvature radius, said fourth lens is formed in a shape so that a surface thereof on the object side has a negative curvature radius, said sixth lens is formed in a shape so that a surface thereof on the image plane side has a positive curvature radius, and said first lens has an Abbe's number \u03bdd 1  so that the following conditional expression is satisfied:\n 40<\u03bd d 1<75.
