Multiple imaging modality light source

Abstract

A light source includes a first LED to provide light of a first light wavelength spectrum along a first light path; a second LED to provide light of a second light wavelength spectrum along a second light path; a dichroic filter for passing light emitted from at least one of the first LED and the second LED and reflecting light emitted from at least one of the first LED and the second LED; an optical filter movable between a first position in which the optical filter receives light from the first light path and a second position of which the optical filter does not receive light from the first light path; a light output; a controller which is capable of switching the light source between a first mode for providing a first light to the light output and a second mode for providing a second light to the light output.
