Spectrometer for the spectral analysis of a specimen

A spectrometer for the spectral analysis of a sample comprising:

• a radiation source for irradiating the sample with electromagnetic radiation;
• a dispersive element for the spatiospectral splitting of the electromagnetic radiation reflected by the sample;
• a measurement window for transmitting the electromagnetic radiation generated by the radiation source to the sample and for transmitting the electromagnetic radiation reflected by the sample to the dispersive element, wherein the electromagnetic radiation generated by the radiation source passes on a first inner beam path from the radiation source to the measurement window, and wherein the electromagnetic radiation reflected by the sample passes on a second inner beam path from the measurement window to the dispersive element;
• a spatially resolving detector for the wavelength-dependent conversion of the spatiospectrally split electromagnetic radiation;
• and
• a deflection mirror arranged on the first inner beam path and on the second inner beam path and serving for jointly deflecting the first inner beam path and the second inner beam path.
