Abstract
A method of analysing a spectral peak obtained by an optical spectrometer is provided. The method comprises imaging a spectral peak using an optics assembly and a detector of the optical spectrometer to generate a detected image of the spectral peak. An image correction function is applied to the detected image of the spectral peak to obtain a corrected image of the spectral peak, wherein the image correction function increases the spectral power density of the spectral peak in the corrected image of the spectral peak. Information representative of the spectral peak is extracted from the corrected image of the spectral peak.
