Abstract

A radiation generation device for generating resulting electromagnetic radiation having an adjustable spectral composition includes: a multitude of radiation elements (configured to generate a radiation element specific electromagnetic radiation, respectively, upon being activated, a first radiation element of the multitude of radiation elements being activatable independently of a second radiation element of the multitude of radiation elements; a dispersive optical element; and an optical opening; the dispersive optical element being configured to deflect the radiation element specific electromagnetic radiations, in dependence on their wavelength and on a position of the radiation element generating the respective radiation element specific electromagnetic radiation, such that a particular spectral range of each of the radiation element specific electromagnetic radiations may exit through the optical opening, so that the spectral composition of the resulting electromagnetic radiation exiting through the optical opening is adjustable by selectively activating the multitude of radiation elements.
