Abstract
A diffusive ultraviolet illuminator is provided. The illuminator can include a reflective mirror and a set of ultraviolet radiation sources located within a proximity of the focus point of the reflective mirror. The ultraviolet radiation from the set of ultraviolet radiation sources is directed towards a reflective surface located adjacent to the illuminator. The reflective surface can diffusively reflect at least 30% the ultraviolet radiation and the diffusive ultraviolet radiation can be within at least 40% of Lambertian distribution. A set of optical elements can be located between the illuminator and the reflective surface in order to direct the ultraviolet radiation towards at least 50% of the reflective surface.
