Imaging lens

An imaging lens, comprising:

• a first lens, wherein the first lens is a lens with a refractive power closest to a magnified side of the imaging lens;
• a second lens with a refractive power;
• a third lens, wherein the third lens is a lens with a refractive power closest to a minified side of the imaging lens;
• and
• an aperture stop disposed between the magnified side and the second lens, wherein the imaging lens includes at least two aspheric lenses and satisfies the following conditions:
• (1) 0.07 mm<dBFL<0.17 mm;
• and
• (2) 0.48<D1/DL<0.77, where dBFL denotes a distance between a focal plane formed by light with a wavelength of 587 nm and a focal plane formed by light with a wavelength of 940 nm on an optical axis of the imaging lens when a subject to be captured is at infinity, D1 is a lens diameter of the first lens, and DL is a lens diameter of the third lens.
