Abstract
An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens, disposed in order from an object side, and a first reflection member and a second reflection member, disposed on an object side of the first lens, each having a freeform surface.
Claims15
An optical imaging system, comprising:
- a first lens, a second lens, a third lens, a fourth lens, and a fifth lens disposed in order from an object side toward an imaging plane;
- and
- a first reflection member and a second reflection member, disposed on an object side of the first lens, each of the first reflection member and the second reflection member having a freeform surface,
- wherein the third lens has a convex object-side surface, and
- wherein the optical imaging system comprises a total of five lenses.
