According to the invention, the radiation sources are all located in the center of the directing means such that the radiation sources are arranged concentrically with respect to one another. The radiation sources can be switched on and off individually, jointly, or in combination. Each radiation source emits electromagnetic radiation within a constant wavelength range when switched on, wherein different radiation sources can emit electromagnetic radiation within different wavelength ranges.
