Spectral analysis system for capturing a spectrum with an optic that forms an optical path,
- wherein spectral analysis system is configured to apply a correction function to a captured spectrum so as to acquire a modified spectrum;
- wherein the correction function is generated by a method for determining a correction function for a spectrum captured by a spectral analysis system, comprising:
- capturing a reference spectrum of a reference radiation source with the spectral analysis system so as to acquire a captured reference spectrum, wherein the spectrum of the reference radiation source comprises a peak with a spectral width that is smaller than a spectral resolution performance of the spectral analysis system,
- creating a correction function from the captured reference spectrum so that, when applying the correction function to captured spectra captured by the spectral analysis system, modified spectra that are less impaired by errors of an optic of the spectral analysis system are acquired.
