Abstract
An optical imaging system includes lenses sequentially disposed from an object side toward an imaging plane and including a refractive power in paraxial regions or edges of the paraxial regions. An object-side surface of a fifth lens of the lenses is planar in a paraxial region and the fifth lens includes a refractive power at an edge of the paraxial region.
Claims16
An optical imaging system, comprising:
- lenses sequentially disposed from an object side toward an imaging plane and comprising a refractive power in paraxial regions or edges of the paraxial regions,
- wherein a third lens, a fourth lens, and a fifth lens of the lenses have refractive indexes greater than refractive indexes of a first lens, a second lens, and a sixth lens of the lenses, and
- wherein an object-side surface of the fifth lens is planar in a paraxial region and the fifth lens comprises a refractive power at an edge of the paraxial region.
An optical imaging system, comprising:
- a first lens comprising a convex object-side surface;
- a second lens comprising a convex object-side surface and a convex image-side surface;
- a third lens comprising a convex object-side surface;
- a fourth lens comprising a convex object-side surface;
- a fifth lens comprising a planar surface on a paraxial region thereof;
- and
- a sixth lens comprising a convex object-side surface,
- wherein the first to sixth lenses are spaced apart and sequentially disposed from an object side toward an imaging plane, and
- wherein the third lens, the fourth lens, and the fifth lens have refractive indexes greater than refractive indexes of the first lens, the second lens, and the sixth lens.
