Abstract
An imaging lens includes a first lens group and a second lens group. The first lens group includes three lenses with refractive powers, where two of three lenses of the first lens group are aspheric lenses. The second lens group includes three lenses with refractive powers, where one of three lenses is an aspheric lens and other two lenses are paired to form a doublet lens. The imaging lens satisfies conditions of 3.0<LT/IMH<3.5 and 1.0<D1/LT<1.08, where IMH is a semi-diagonal image height of the imaging lens, D1 is a lens diameter of a lens closest to an object side of the imaging lens, and LT is a distance measured along an optical axis between two outermost lens surfaces with refractive powers at opposite ends of the imaging lens.
