Abstract
The present invention relates to a spectrometer for spectral analysis of electromagnetic radiation. The spectrometer comprises an entry slit for entry of the electromagnetic radiation to be analysed and an imaging grating for diffraction of the electromagnetic radiation which has entered. The spectrometer additionally comprises a detector extending at least in one direction to detect the diffracted electromagnetic radiation, and also a support plate in which the entry slit is located. The spectrometer further comprises a housing which is mounted on the support plate, covers the detector and the entry slit and supports the imaging grating. According to the invention the spectrometer further comprises at least three floating bearings for floating mounting of the housing on the support plate, the floating bearings each enabling a displacement between the housing and the support plate on a directional axis and being distributed about a central axis of the housing.
