Patent number: 10634875Abstract: It is possible to (i) cause a sixth lens to more effectively correct various aberrations and (ii) make an optical overall length shorter. A first lens (L1) has positive refractive power. A fifth lens (L5) and a sixth lens (L6) each have negative refractive power. An object-side surface (L1F) of the first lens (L1) is a convex surface. At least one of an object-side surface and an image plane-side surface of each of a second lens (L2), a third lens (L3), a fourth lens (L4), and the fifth lens (L5) is an aspheric surface. An object-side surface (L6F) of the sixth lens (L6) is a concave surface and is an aspheric surface. An image plane-side surface (L6R) of the sixth lens (L6) is an optically planar surface throughout a region corresponding to an effective diameter of the image plane-side surface (L6R) of the sixth lens (L6).Type: GrantFiled: April 4, 2017Date of Patent: April 28, 2020Assignees: SHARP KABUSHIKI KAISHA, KANTATSU Co., LTDInventors: Norimichi Shigemitsu, Yoshihito Ishizue, Hisao Fukaya, Kaoru Yamazaki, Shingo Yuza
