1. A pupil separation system comprising:
an input surface;
a central portion including a set of dichroic mirrors;
a first reflective surface disposed laterally with respect to the central portion;
a second reflective surface disposed laterally with respect to the central portion; and
an output surface including:
a central surface operable to transmit light in a first wavelength range;
a first peripheral surface adjacent the central surface and operable to transmit light in a second wavelength range, wherein the light in the second wavelength range is reflected by the set of dichroic mirrors before being reflected by the first reflective surface; and
a second peripheral surface adjacent the central surface and opposite to the first peripheral surface, wherein the second peripheral surface is operable to transmit light in a third wavelength range, wherein the light in the third wavelength range is reflected by the set of dichroic mirrors before being reflected by the second reflective surface.
