Abstract

A method is provided for calibrating a spectrometer device used for Raman scattering analysis. A predetermined dispersion curve for a diffraction grating or spectrograph of the spectrometer device is modified based on spectrum data associated with detected dispersed light from a calibration light source to produce a modified dispersion curve. The wavelength of a Raman light source on a light detection device is determined. Calibration data for the spectrometer device is computed from the Raman line peak positions for the first chemical, the wavelength on the detection device of the Raman light source and the modified dispersion curve.
