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.
Claims16
An optical imaging system comprising:
- a first lens comprising a convex image-side surface;
- a second lens comprising a refractive power;
- a third lens comprising a refractive power;
- and
- a fourth lens comprising a refractive power,
- wherein the first to fourth lenses are sequentially disposed from an object side toward an imaging plane,
- 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 the image sensor, and
- wherein a thickness of the second lens is greater than a distance from an image-side surface of the third lens to an object-side surface of the fourth lens.
