Patent ID: 10859800

Abstract:
Compact imaging lens which maintains low-profileness, wide field of view, and properly corrects various aberrations. Imaging lens includes first lens having positive refractive power and convex surface facing object side near an optical axis, second lens having negative refractive power and concave surface facing image side near optical axis, third lens having positive refractive power and concave surface facing image side near optical axis as double-sided aspheric lens, fourth lens having meniscus shape with positive refractive power and concave surface facing object side near optical axis, fifth lens as double-sided aspheric lens, and sixth lens having negative refractive power and concave surface facing image side near optical axis as double-sided aspheric lens, and conditional expression is satisfied: (1) 0.6<Σd/f<1.0, where Σd denotes distance along optical axis from object-side surface of first lens to image-side surface of sixth lens, and f denotes focal length of overall optical system of imaging lens.
