A spread primary reflector for a UV curing lamp employs a substrate that has been faceted. The facets may be produced by means of stamping, etching, or a combination of chemical-mechanical processes. The faceting randomizes the focusing effects of the primary reflector's elliptical curvature while maintaining a total directed energy output and hence a uniform irradiance of a work product. The reflector may be made of a stand-alone reflective material with a preformed faceting pattern, such as from a metal substrate and coated with an optical coating to tailor the reflective properties of the surface of the substrate.
