Abstract
An optical imaging system includes a first lens having refractive power; a second lens having refractive power; a third lens having refractive power and cemented to the second lens; a fourth lens having refractive power; a fifth lens having refractive power and cemented to the fourth lens; a sixth lens having refractive power; a seventh lens having refractive power; and an eighth lens having refractive power. The first to eighth lenses are sequentially disposed in numerical order beginning with the first lens from an object side of the optical imaging system toward an imaging plane of the optical imaging system.

An optical imaging system comprising:
- a first lens having refractive power;
- a second lens having refractive power;
- a third lens having refractive power and cemented to the second lens;
- a fourth lens having refractive power and a concave object-side surface;
- a fifth lens having refractive power and cemented to the fourth lens;
- a sixth lens having refractive power;
- a seventh lens having refractive power and a convex object-side surface;
- and
- an eighth lens having refractive power;
- wherein the first to eighth lenses are sequentially disposed in numerical order beginning with the first lens from an object side of the optical imaging system toward an imaging plane of the optical imaging system.
An optical imaging system comprising a first lens, a second lens, a third lens, a stop, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens sequentially disposed in numerical order beginning with the first lens from an object side of the optical imaging system toward an imaging plane of the optical imaging system,
- wherein the fourth lens has a concave object-side surface and the seventh lens has a convex object-side surface.
