Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. An optical imaging system, comprising:
a first lens, a second lens, a third lens, a fourth lens, a fifth lens having a convex image-side surface in a paraxial region thereof, and a sixth lens sequentially arranged in numerical order from an object side of the optical imaging system toward an imaging plane of the optical imaging system and each having a refractive power,
wherein:
a radius of curvature of an object-side surface of the sixth lens is greater, in a sense of more positive, than a radius of curvature of an object-side surface of the first lens,
an entire field of view of the optical imaging system is 50° or greater, and
TTL/f<1.0, where TTL is a distance from an object-side surface of the first lens to the imaging plane, and f is an overall focal length of the optical imaging system.
