1. A pupil separation system comprising:
an input surface;
a central portion including one or more dichroic mirrors;
a reflective surface disposed laterally with respect to the central portion;
a second portion disposed between the central portion and the reflective surface and including a second peripheral output surface, wherein the second portion comprises a second dichroic mirror; and
an output surface including:
a central surface operable to transmit light in a first wavelength range; and
a peripheral surface operable to transmit light in a second wavelength range different from the first wavelength range, wherein the light in the second wavelength range is reflected by the one or more dichroic mirrors before being reflected by the reflective surface.
