OPTICAL IMAGING SYSTEM

An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens sequentially disposed from the first lens to the fifth lens from an object-side of the imaging system to an image-side of the imaging system and each having refractive power. The fourth lens...

Abstract An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens sequentially disposed from the first lens to the fifth lens from an object-side of the imaging system to an image-side of the imaging system and each having refractive power. The fourth lens has a convex object-side surface and an expression 0.7<TL/f<1.0 is satisfied, where TL is a distance from an object-side surface of the first lens to an imaging plane, and f is an overall focal length of the optical imaging system.
