Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 4:
5. An optical imaging system comprising:
three or more lenses disposed on an optical axis,
wherein one or more of the three or more lenses comprises one or more anamorphic lenses each having at least one surface comprising a first profile including the optical axis different from a second profile including the optical axis, and a first length different from a length of the second profile,
wherein 0<|(fx−fy)/fx|<0.01 in which fx is a focal length of the one or more anamorphic lenses calculated based on a radius of curvature of the first profile, and fy is a focal length of the one or more anamorphic lenses 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.
