摘要： A low-profile, high-resolution, low-cost imaging lens comprises five optical elements arranged from an object side: a first positive optical element group including a first positive lens having a convex object-side surface as a first optical element and a second negative lens having a concave image-side surface as a second optical element; a second positive optical element group including a third positive lens having a convex image-side surface as a third optical element; and a third negative optical element group including a fourth negative double-sided aspheric lens having a concave image-side surface as a fourth optical element. The image-side surface of the fourth lens has at least one pole-change point off an optical axis. A double-sided aspheric aberration correction optical element with virtually no refractive power as a fifth optical element is located in an air gap nearer to the image plane than the first optical element group.
