Abstract
An optical imaging system includes a first lens having positive refractive power, a second lens having positive refractive power, a third lens having positive refractive power, and a fourth lens having positive refractive power, and an F No. of the optical imaging system is equal to or less than 1.0. The optical imaging system is capable of achieving miniaturization while capturing an image at low illumination.

An optical imaging system, comprising:
- a first lens having a refractive power;
- a second lens having a refractive power;
- a third lens having a convex object-side surface;
- and
- a fourth lens having a convex object-side surface,
- wherein the first to fourth lenses are sequentially disposed from an object side to an image surface of the optical imaging system,
- wherein the optical imaging system has a total number of four lenses with refractive power, and
- wherein 1.580 <Nd1 <1.640, where Nd1 is a refractive index of the first lens.
