Abstract
An apparatus for providing a light output to an optical guide for illumination of an imaged object including a plurality of solid state light-emitting sources each of which are independently powered and independently controlled, each light-emitting source emitting light at a wavelength which is different from the wavelength emitted by the other light-emitting sources. The apparatus also includes a heat sink configured to thermally couple the plurality of solid state light-emitting sources and provide conduction of heat generated by the plurality of solid state light-emitting sources. The apparatus further includes an optical elements to collect, collimate, and combine the emissions from the plurality of solid state light-emitting sources into a combined beam of light to be optically coupled to the light guide.
