Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A lens, wherein
a first profile in a first direction intersecting an optical axis and a second profile in a second direction intersecting the optical axis are different from each other,
a length of the first profile in the first direction is different from a length of the second profile in the second direction,
0<|(fx−fy)/fx|<0.01 in which fx is a focal length of the lens calculated based on a radius of curvature of the first profile, and fy is a focal length of the lens calculated based on a radius of curvature of the second profile, and
wherein 0.2<|(Rx1−Ry1)/Rx2|<2.0 in which Rx1 is a radius of curvature of an object-side surface of the first profile, Ry1 is a radius of curvature of an object-side surface of the second profile, and Rx2 is a radius of curvature of an image-side surface of the first profile.
