1. An optic for mixing and shaping electromagnetic radiation comprising:
a mixing pipe optically coupled to one or more radiation sources, the one or more radiation sources configured to generate electromagnetic radiation; and
a reflector body integrally secured to the mixing pipe, the reflector body comprising a first planar internal surface configured to receive the electromagnetic radiation from the one or more radiation sources and reflect or refract the electromagnetic radiation as reflected electromagnetic radiation, the first planar internal surface being a conical planar shape formed within the reflector body, a portion of the first planar internal surface of the reflector body including a first reflective material, and a second planar internal surface configured to receive the reflected electromagnetic radiation and reflect or refract the reflected electromagnetic radiation, a portion of the second planar internal surface of the reflector body including a second reflective material;
wherein at least a portion of the reflected electromagnetic radiation is configured to exit the reflector body through the first planar internal surface.
