ABSTRACT:
Systems and techniques for contemporaneous Raman and photoluminescence spectroscopy. Light that has interacted with a sample is dispersed to separate wavelength components, including Raman and photoluminescence components. A first array detector is positioned to receive Raman components, and a second array detector is positioned to receive Raman components. The first array detector and the second array detector may comprise the same detector material, or different detector materials.
