Abstract
A device has a light source apparatus, which, as required, feeds white continuous light or sequential colored light by means of a filter device having several color surface regions and two filter discs which can be rotary driven, into a particular endoscope. One filter disc is provided with the color segments red, green and white and the other filter disc is provided with the color segments blue and white to achieve a simplified and structurally compact light source apparatus, both filter discs being arranged to be rotatable on a common rotary axis and adjustable relative to one another and fixable such that the white color segment of one filter disc covers the blue color segment of the other filter disc in a first operating position of the filter discs, and the white color segment of one filter disc is aligned to be axis-parallel with the white color segment of the other filter disc in a second operating position of the filter discs.
