Abstract
An optical imaging system includes a first lens having refractive power, a second lens having refractive power and having a convex object-side surface, a third lens having refractive power and having a convex object-side surface, a fourth lens having refractive power, a fifth lens having refractive power, and a sixth lens having negative refractive power. The optical imaging system satisfies 100°≤FOV, and −2.0<{IMGHT/(f*tan(FOV/2))−1}*100<2.0, where FOV is a field of view of the optical imaging system, IMGHT is half of a diagonal length of an imaging plane, and f is a focal length of the optical imaging system.
