1. An optical imaging system, comprising:
a first lens comprising a concave image-side surface;
a second lens comprising a refractive power;
a third lens comprising a refractive power;
a fourth lens comprising a convex object-side surface;
a fifth lens comprising a refractive power; and
a sixth lens comprising a refractive power,
wherein the first to sixth lenses are sequentially disposed from an object side toward an imaging plane,
wherein the optical imaging system has a total of six lenses with refractive power,
wherein a thickness of the first lens is greater than a thickness of the second lens,
wherein a radius of curvature of an object-side of the third lens is greater than a radius of curvature of an object-side of the second lens,
wherein a radius of curvature of an image-side surface of the third lens is greater than a radius of curvature of an object-side surface of the sixth lens, and
wherein a thickness along an optical axis of the fifth lens is greater than a thickness along the optical axis of the sixth lens.
