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.

Abstract: An optical system for use with a multi-channel wide field imaging system, the optical system including an objective lens, a dichroic element to split light into a first wavelength range and a second wavelength range, the dichroic element positioned to receive near parallel chief rays from the objective lens, a first channel lens system to receive light of the first wavelength range from the dichroic element; and a second channel lens system to receive light of the second wavelength range from the dichroic element.

Abstract: An imaging device may include a first illumination port to output first light having a first illumination distribution at a target to illuminate the target, a second illumination port to output second light having a second illumination distribution at the target to illuminate the target, the second illumination distribution being substantially similar to the first illumination distribution at the target, the second illumination port being spaced apart from the first illumination port, the first and second illumination distributions being simultaneously provided to the target and overlapping at the target. The illumination from the first and second ports may be matched to a same aspect ratio and field of view coverage as the imaging field of view.
