Abstract
A spectrometer arrangement is disclosed for the determination of a radiation wavelength of radiation emitted from a radiation source to be measured. The arrangement includes a diffraction grating on which the radiation of the radiation source to be measured is incident at a predetermined angle, wherein the diffraction grating is provided by a reflection grating having a variable lattice constant. The arrangement also includes a radiation detector for receiving from the radiation source to be measured radiation diffracted at a predetermined angle at the diffraction grating.
