1. A photocatalytic dielectric combiner, comprising:

  • a) a substrate;

    b) a plurality of dielectric layers comprised of alternating layers of a first dielectric material and a second dielectric material, each layer having a high index of refraction, deposited upon the substrate for reflecting UV within a predetermined spectrum and otherwise transmitting light wherein the index of refraction of both the first dielectric material and the second dielectric material are different from each other, and each is greater than 2.0; and

    c) a photocatalytic coating of TiO2 disposed on the dielectric layer opposite the substrate designed to induce photocatalytic reactions in the presence of UV to provide a self-cleaning, self-sanitizing, and self-deodorizing combiner surface.
