Funded by NSF CCLI program, Award No. 0941364, the Raman Imaging and Spectroscopy Laboratory is equipped with a Nicolet DXR Dispersive Raman Spectrometer and Microscope from Thermo Scientific with three lasers:
- 532 nm solid state laser,
- 633 nm He-Ne gas laser, and
- 780 nm solid state laser, all 10 mW power.
The confocal spectrometer system is based on an inverted optical microscope with diffraction-limited amplification.

Raman Spectroscopy enables identifying chemical substances through the analysis of vibrational modes of molecules.
Surface Enhanced Raman Spectroscopy (SERS) offers high amplification of the Raman signal.
Surface Enhanced Resonance Raman Spectroscopy (SERRS) offers even higher amplfication allowing one to analyze single molecules.
