Abstract
The invention relates to a method and a spectrometer for wavelength-dependent measurement of radiation in the range of UV light and visible light, with an entry gap, a dispersive element and a number of sensors comprising pixels, wherein a light path runs inside the spectrometer from the entry slot to the sensors and an imaging element is provided, which focusses the radiation on the sensors, in the case of which a means for defocussing the radiation is provided, which is activatable for the purpose of calibration.
