Abstract
An optical imaging system includes a first lens having a convex image-side surface, a second lens having a concave object-side surface, a third lens, a fourth lens, and a fifth lens disposed sequentially from an object side. The optical imaging system satisfies 4.8<f/IMG_HT<9.0, where f is a focal length of the optical imaging system, and IMG_HT is half a diagonal length of an imaging surface of an image sensor.
Claims18
An optical imaging system comprising:
- a first lens comprising a convex image-side surface, a second lens comprising a concave object-side surface, a third lens, a fourth lens, and a fifth lens disposed sequentially from an object side,
- wherein 4.8<f/IMG_HT<9.0, where f is a focal length of the optical imaging system, and IMG_HT is half a diagonal length of an imaging surface of an image sensor.
An optical imaging system comprising:
- a first prism, a first lens, a second lens, a third lens, a fourth lens, and a fifth lens disposed sequentially from an object side,
- wherein 0.02<AL1/(PTTL)2<0.07, where AL1 is an area in which an effective diameter of the first lens is projected onto an imaging plane, and PTTL is a distance from a reflective surface of the first prism to the imaging plane.
