1. An optical imaging system comprising:
a first lens, a second lens, and a third lens disposed on an optical axis,
wherein one or more of the first to third 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, and
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.
