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.
Claims10
An optical imaging system, comprising:
- a first lens comprising positive refractive power and a concave image-side surface;
- a second lens comprising positive refractive power;
- a third lens comprising negative refractive power and a convex object-side surface;
- a fourth lens comprising a refractive power;
- a fifth lens comprising a refractive power;
- a sixth lens comprising negative refractive power, a convex object-side surface, and an inflection point formed on an image-side surface of the sixth lens,
- wherein the first to sixth lenses are sequentially disposed from an object side toward an imaging plane,
- wherein the fourth lens has a concave object-side surface or the fifth lens has a concave image-side surface,
- wherein a thickness of the first lens is greater than a thickness of the second lens,
- wherein a distance from the image-side surface of the first lens to an object-side surface of the second lens is greater than a distance from the image-side surface of the fifth lens to the object-side surface of the sixth lens, and
- wherein a radius of curvature of an object-side of the third lens is greater than a radius of curvature of an object-side of the second lens.
