Abstract
Raman spectrometers are provided that illuminate a sample with two or more different beams of light, each characterized by a different primary frequency. Scattered light from the sample is separated into multiple Raman spectra, one for each primary frequency. The multiple Raman spectra can be evaluated individually, or they can be added together to form a composite spectrum that is then evaluated.
