1. A prism for an optical imaging system, comprising:
an incident surface on which light is incident;
an emission surface from which light is emitted;
a reflective surface configured to reflect light incident to the incident surface to the emission surface;
a discontinuous portion disposed on an edge of one of the incident surface, the emission surface, and the reflective surface, and disposed at one or both of a boundary portion between the incident surface and the reflective surface and a boundary portion between the emission surface and the reflective surface; and
a first protrusion disposed on both of side surfaces of the prism,
wherein the prism is configured to rotate about the first protrusion,
wherein the first protrusion and the side surfaces of the prism have a similar shape, and
wherein the reflective surface is configured to have a wavefront aberration different from wavefront aberrations of the incident surface and the emission surface.
