1. An optical imaging system, comprising:
a prism
a first lens comprising positive refractive power;
a second lens comprising negative refractive power;
a third lens comprising positive refractive power; and
a fourth lens comprising positive refractive power,
wherein the prism and the first to fourth lenses are sequentially disposed in order from an object side to an image plane,
wherein the optical imaging system has a total number of four lenses, and
wherein 1.0<PTTL/f<2.0, where PTTL is a distance from the reflective surface of the prism to the imaging plane and f is a focal length of the optical imaging system.
