Abstract
An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens. The first lens includes a convex object-side surface and a concave image-side surface. The second lens includes a concave object-side surface and a concave image-side surface. The third lens includes a concave object-side surface. The fourth lens includes a concave object-side surface. The fifth lens includes a concave object-side surface and a concave image-side surface. The first to fifth lenses are sequentially disposed from an object side toward an imaging plane.

An optical imaging system comprising:
- a first lens having a refractive power;
- a second lens having a convex object-side surface;
- a third lens having a refractive power;
- a fourth lens having positive refractive power;
- and
- a fifth lens having negative refractive power,
- wherein the first to fifth lenses are sequentially disposed from an object side toward an imaging plane,
