Patent ID: 11927731
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 8:
9. An optical imaging system comprising:
an anamorphic lens comprising a radius of curvature Rx1 of an object-side surface of a first profile including an optical axis, and a radius of curvature Ry1 of the object-side surface of a second profile including the optical axis, different from each other,
wherein a length of the first profile and a length of the second profile are different from each other,
wherein 0<|(fx−fy)/fx|<0.01 in which fx is a focal length of the anamorphic lens calculated based on the radius of curvature of the first profile of the anamorphic lens and fy is a focal length of the anamorphic lens calculated based on the radius of curvature of the second profile of the anamorphic lens, and
wherein 0.2<|(Rx1−Ry1)/Rx2|<2.0 in which Rx2 is a radius of curvature of an image-side surface of the first profile.
