Patent ID: 11460679

Abstract:
There is provided an imaging lens with high-resolution which satisfies demand of wide field of view, low-profileness and low F-number in well balance, and excellently corrects aberrations. An imaging lens comprises, in order from an object side to an image side, a first lens, a second lens having negative refractive power near the optical axis, a third lens having a convex surface facing the image side near the optical axis, a fourth lens and a fifth lens, wherein said first lens has negative refractive power near the optical axis, an image-side surface of said fifth lens has a convex surface facing the image side near the optical axis, and below conditional expressions are satisfied: 3.00<(T4/f)×100<5.900.40<f2/f5<1.45 where  T4: a distance along the optical axis from the image-side surface of the fourth lens to the object-side surface of the fifth lens,  f: a focal length of the overall optical system of the imaging lens,  f2: a focal length of the second lens,  f5: a focal length of the fifth lens.
