Abstract
An optical imaging system includes a first lens having a positive refractive power and a convex object-side surface; a second lens having a negative refractive power, a convex object-side surface, and a concave image-side surface; a third lens having a negative refractive power; a fourth lens having a refractive power; a fifth lens having a negative refractive power; and a sixth lens having a positive refractive power. 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, and are the only lenses having a refractive power in the optical imaging system.
