Claim:
1. An illuminator comprising: at least one ultraviolet radiation source configured to generate ultraviolet radiation; a reflective cavity comprising a plurality of surfaces, wherein the at least one ultraviolet radiation source is located within the reflective cavity, and wherein at least one of the plurality of surfaces is formed of a first material configured to diffusively reflect at least 70% of the ultraviolet radiation, and at least one of the plurality of surfaces is formed of a second material configured to transmit at least 30% of the ultraviolet radiation through the second material and out of the reflective cavity and reflect at least 10% of the ultraviolet radiation, wherein the second material is patterned to include a plurality of holes configured to increase uniformity of the ultraviolet radiation exiting the reflective cavity; and a set of reflecting mirrors located within the reflective cavity and configured to diffusively reflect the ultraviolet radiation, wherein each reflecting mirror is patterned to include a plurality of holes configured to improve an intensity distribution of the ultraviolet radiation exiting the reflective cavity.
