1. An optical imaging system, comprising:
a first lens comprising a refractive power;
a second lens comprising a refractive power;
a third lens comprising a convex object-side surface and a concave image-side surface in a paraxial region;
a fourth lens comprising a convex object-side surface and a concave image-side surface in a paraxial region;
a fifth lens comprising a convex image-side surface; and
a sixth lens comprising negative refractive power, and a concave object-side surface in a paraxial region,
wherein the first to sixth lenses are sequentially disposed in ascending numerical order from an object side of the optical imaging system toward an imaging plane of the optical imaging system,
wherein an absolute value of a curvature of the object-side surface of the second lens is greater than an absolute value of a curvature of an image-side surface of the first lens,
wherein a thickness of the fifth lens is greater than a thickness of the sixth lens, and
wherein an Abbe number of the third lens is 50 or greater.
