Abstract:
There is provided an imaging lens having small ratio of the total track length to the focal length of an overall optical system, reducing telephoto ratio, properly correcting aberrations and having the high resolution. An imaging lens comprises five optical elements, in order from an object side to an image side, comprising, a first lens as a first optical element having positive refractive power, a second lens as a second optical element having negative refractive power and a convex surface facing the object side near an optical axis, a third lens as a third optical element having the refractive power, and a fourth lens as a fourth optical element having refractive power and the convex surface facing the object surface near the optical axis, wherein and an aberration correction optical element as a fifth optical element are arranged between said third lens and said fourth lens, said aberration correction optical element has both flat surfaces near the optical axis and aspheric surfaces.

Claim (Index 3):
The imaging lens comprising five optical elements according to  claim 1 , wherein a below conditional expression (2) is satisfied:\n 2.00<( d 3/ TTL )\u00d7100<12.65\u2003\u2003(2) where TTL: distance along an optical axis from an object-side surface of the first lens to an image plane, and d3: thickness on the optical axis of the third lens.
