Abstract
An imaging lens system is provided. The imaging lens system includes a lens group including a plurality of lenses; and an optical path conversion member disposed between the lens group and an imaging plane. The lens group may include a first lens, a second lens, a third lens, and a fourth lens sequentially disposed from an object side toward the imaging plane. The optical path conversion member may reflect light emitted from the lens group two or more times to increase a rear focal length of the lens group (or a distance from an image-side surface of a lens disposed on a rearmost side of the lens group to the imaging plane).
Claims18
An imaging lens system, comprising:
- a first lens, a second lens, a third lens, a fourth lens, and an optical path conversion member sequentially disposed from an object side toward an imaging plane,
- wherein 0.70<PL/TTL<0.90,
- where PL is a distance from an incident surface of the optical path conversion member to an exit surface of the optical path conversion member, and TTL is a distance from an object-side surface of the first lens to the imaging plane.
An imaging lens system, comprising:
- a first lens, a second lens, a third lens, a fourth lens, and an optical path conversion member sequentially disposed from an object side toward an imaging plane,
- wherein 0.80<f/PL<1.20,
- where PL is a distance from an incident surface of the optical path conversion member to an exit surface of the optical path conversion member, and f is a focal length of the imaging lens system.
An imaging lens system, comprising:
- a first lens, a second lens, a third lens, a fourth lens, and an optical path conversion member sequentially disposed from an object side toward an imaging plane,
- wherein 0.70<PU/TTL<0.90, and
- wherein 0.10<TL14/PL<0.30,
- where PL is a distance from an incident surface of the optical path conversion member to an exit surface of the optical path conversion member, TTL is a distance from an object-side surface of the first lens to the imaging plane, and TL14 is a distance from an object-side surface of the first lens to an image-side surface of the fourth lens.
