ABSTRACT:
The invention relates to a transparent zero distortion photocatalytic dielectric combiner housing a series of hard durable thin films that reflect 98% of UV, with a plurality of dielectric layers having indices of refraction greater than 2.0 but otherwise is transmissive to light at all wavelengths. The photocatalytic dielectric combiner selectively reflects and concentrates UV from sources such as light fixtures or sunlight within a narrow range of wavelengths on the outer surface of the combiner element, promoting photocatalytic oxidation to decompose bacteria and contaminants, making surfaces the combiner is placed upon self-cleaning, self-sanitizing, and self-deodorizing. The invention is suitable for windows, counter tops, door hardware, plumbing fixtures, and the like. In addition, when a hard, thin-film, decorative, reflective layer is added to the combiner element and placed on top of a smooth hard leveling organic polymer it can provide a viable alternative to electroplated decorative finishes, with a self-sanitizing, self-cleaning, decorative coating. Preferably the film is deposited by alternating low pressure environment deposition techniques.
