Abstract
An optical imaging system includes a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a negative refractive power, a fourth lens, a fifth lens, and a sixth lens having a positive refractive power and having a convex image-side shape, sequentially arranged in a direction from an object side of the optical imaging system to an imaging plane of the optical imaging system.

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