Patent ID: 11262543

Abstract:
There is provided an imaging lens with excellent optical characteristics which satisfies demand of the wide field of view, the low-profileness and the low F-number. An imaging lens comprises, in order from an object side to an image side, a first lens having a convex surface facing the object side near an optical axis and positive refractive power, a second lens having negative refractive power near the optical axis, a third lens, a fourth lens, a fifth lens being double-sided aspheric lens, and a sixth lens having a concave surface facing the image side near the optical axis and negative refractive power, wherein an image-side surface of the sixth lens is formed as an aspheric surface having at least one off-axial pole point, an image-side surface of the third lens is a convex surface facing the image side near the optical axis, the fourth lens has positive refractive power near the optical axis, and predetermined conditional expressions are satisfied.
