Micro- Raman Spectroscopy

Our Laboratory is equipped with an Horiba Labram Evolution Raman Spectrometer

Key features:

  • Two laser wavelengths (532, 633 nm)
  • Dual gratings (600 g/mm and 1800 g/mm)
  • Long-working-distance microscope objectives (Mitutoyo, 10x, 20x, 50x)
  • 0.9-m spectrograph, thermoelectrically cooled CCD detector
  • Confocal imaging capabilities
  • Spectral resolution of better than 2 cm-1
  • 2D mapping capabilities (Duoscan, Swift mapping)
  • A library of 24,000 reference spectra for automated identification of unknowns.
