Abstract
A device for performing Raman spectroscopy measurements that incorporate Raman Shift calibration and related method for carrying out the Raman Shift calibration are disclosed. The device comprises of one or more Raman shift reference materials with one or more Raman bands, the positions of which are pre-determined to a high degree of accuracy within a useful temperature range. The device further comprises a sensor to measure the temperature of the one or more reference materials to provide accurate reference values for the Raman shift calibration. When used with the measured spectrum of the reference materials, an accurate Raman Shift calibration function of the device can be generated.
