Classification: CPC G | IPC G

Claim 16:
17. An optical imaging system, comprising:
a first lens, a second lens, a third lens, a fourth lens having a concave object-side surface in a paraxial region, and a fifth lens having a convex image-side surface in a paraxial region,
wherein the first to fifth lenses are sequentially disposed from an object side to an imaging plane,
wherein at least one of the first to fifth lenses are aspheric and formed using a glass material,
wherein the first lens comprises a greatest Abbe number in the optical imaging system,
wherein the third lens comprises a greatest refractive index in the optical imaging system,
wherein a thickness along an optical axis of the second lens is greater than a thickness along an optical axis of the third lens,
wherein a radius of curvature of an object-side surface of the second lens is greater than a radius of curvature of an image-side surface of the first lens and a radius of curvature of an image-side surface of the third lens, and
wherein a radius of curvature of an image-side surface of the fourth lens is greater than a radius of curvature of an object-side surface of the fourth lens.
