The system can include an optical housing configured to secure the optic along with a diffuser component arranged between the optic and the exit lens of the optical housing. The optic includes an integrally formed mixing pipe and reflector body configured to mix and shape radiation for superior near field and far field mixing. The mixing pipe is optically coupled to one or more radiation sources. The reflector body includes a first internal surface configured to receive the radiation from the one or more radiation sources and reflect or refract the radiation, and a second internal surface configured to receive the reflected radiation and reflect or refract the radiation, wherein at least a portion of the reflected radiation is configured to exit the reflector body through the first internal surface. ## Claims ### Claim 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 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, a portion of the first internal surface of the reflector body including a first reflective material, and a second internal surface configured to receive the reflected electromagnetic radiation and reflect or refract the reflected electromagnetic radiation, a portion of the second 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 internal surface. ### Claim 2 (depends on 1) The optic of claim 1, where the one or more radiation sources are Light Emitting Diodes (LEDs) or Color LEDs. ### Claim 3 (depends on 1) The optic of claim 1, wherein the reflector body is formed with a body material where the body material is polycarbonate. ### Claim 4 (depends on 1) The optic of claim 1, wherein the portion of the first internal surface that comprises the first reflective material includes a portion of the first internal surface proximate an imaginary optical axis arranged through the mixing pipe and the reflector body and substantially concentric with the reflector body. ### Claim 5 (canceled) ### Claim 6 (depends on 1) The optic of claim 1, wherein the second reflective material is disposed along the entire second internal surface. ### Claim 7 (depends on 1) The optic of claim 1, wherein the mixing pipe has a cross-sectional profile, wherein the cross-sectional profile is selected from at least one of: square, circular, hexagonal, and octagonal. ### Claim 8 An optical system for mixing and shaping electromagnetic radiation comprising: an optical housing; a diffuser component; an optic, the optic 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 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, a portion of the first internal surface of the reflector body comprises a first reflective material, and a second internal surface configured to receive the reflected electromagnetic radiation and reflect or refract the reflected electromagnetic radiation, a portion of the second 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 internal surface, and wherein the reflected electromagnetic radiation that exits the reflector body is configured to pass through the diffuser component into a surrounding environment. ### Claim 9 (depends on 8) The optical system of claim 8, where the one or more radiation sources are Light Emitting Diodes (LEDs) or Color LEDs. ### Claim 10 (depends on 8) The optical system of claim 8, wherein the reflector body is formed with a body material where the body material is polycarbonate. ### Claim 11 (depends on 8) The optical system of claim 8, wherein the portion of the first internal surface that comprises the first reflective material includes a portion of the first internal surface proximate an imaginary optical axis arranged through the mixing pipe and the reflector body and substantially concentric with the reflector body. ### Claim 12 (depends on 8) The optical system of claim 8, wherein the second reflective material is disposed along the entire second internal surface. ### Claim 13 (depends on 8) The optical system of claim 8, wherein the mixing pipe has a cross-sectional profile, wherein the cross-sectional profile is selected from at least one of: square, circular, hexagonal, and octagonal.
