Horiba Jobin Yvon LabRam ARAMIS
Optical Spectroscopy
Primary Training Contact

The Horiba Jobin Yvon LabRam ARAMIS is a fully automated Raman microscope.  Raman spectroscopy provides highly specific and non-destructive information on molecular vibrations.  There is no  need for sample preparation - the sample is simply placed under the microscope optics and measured.  This system is also equipped with a Photoluminescence detection package.


Raman and PL Spectroscopy for:

  • Pharmaceuticals (compound distribution, phases, combinatorial chemistry, etc.)
  • Semiconductors (stress, contamination, superlattice structure, doping effects, etc.)
