Confocal Raman Microscopy Service Center
Chemistry Building, room 241

The Instrument

• Renishaw InVia Confocal Raman Microscope (www.renishaw.com) 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.
