Abstract
Official abstract text for this publication.
An illumination device includes at least four semiconductor radiation sources ( 18 ) for emitting optical radiation in respectively different emission wavelength ranges. At least one color splitter ( 22.1, 22.2, 22.3 ), which is reflective for optical radiation of the respective semiconductor radiation source ( 18 ), is assigned to each of at least three of the semiconductor radiation sources ( 18 ). The semiconductor radiation sources ( 18 ) and the color splitters ( 22.1, 22.2, 22.3 ) are arranged such that the optical radiation, which is emitted in each case from each of the semiconductor radiation sources ( 18 ), is coupled into a common illumination beam path section ( 24 ). In each case, one collimating unit ( 20.1, 20.2, 20.3, 20.4 ), which collimates the optical radiation emitted by the respective semiconductor radiation source ( 18 ), is arranged in the beam path sections from the semiconductor radiation sources ( 18 ) to the color splitters ( 22.1, 22.2, 22.3 ).
