Classification: CPC G | IPC G

Claim 0:
1. An optical imaging system comprising:
a first lens comprising a refractive power;
a second lens comprising positive refractive power and a convex object-side surface along an optical axis;
a third lens comprising a refractive power;
a fourth lens comprising a convex object-side surface along the optical axis;
a fifth lens comprising a refractive power and a convex object-side surface along the optical axis; and
a sixth lens comprising negative refractive power,
wherein the optical imaging system comprises a total of six lenses and the first to sixth lenses are sequentially disposed from an object side to an imaging plane,
wherein 0.7<R6/f, where f is an overall focal length of the optical imaging system and R6 is a radius of curvature of an object-side surface of the third lens, and
wherein a thickness of the fifth lens along the optical axis is greater than a thickness of the second lens along the optical axis.
