Abstract
The high intensity illuminator of the invention includes a mounting fixture, a receiving surface spaced from the mounting fixture, and a plurality of semiconductor illumination sources which are implemented, most preferably, by light emitting diodes or laser diodes. Each illumination source is operable for emitting an outwardly-diverging illumination cone along an axis of illumination of the source at a predetermined illumination wavelength. The plural illumination sources are mounted on the mounting fixture such that their illumination cones are overlappingly coincident on a selected portion of the receiving surface to provide at the receiving surface portion a highly uniform illumination of high intensity at the predetermined wavelength.
