Confocal Raman Microscopy Service Center
Chemistry Building, room 241

The Instrument

  • Renishaw InVia Confocal Raman Microscope ( consisting of a tandem microscope-spectrograph capable of detecting Raman and luminescence spectra using a Peltier-cooled charge coupled device (CCD) detector.
  • Two available excitation wavelengths: 785nm and 514 nm.
  • Spectral resolution is better than 0.5cm-1 in the visible region of the spectrum.
  • 100cm-1 low-shift performance.
  • Confocal resolution better than 2.0µm when using x100 objective lens.
