Raman spectroscopy

The Horiba LabRAM Soleil Raman Microscope is a confocal Raman microscope used for spectral imaging and analysis. It combines Raman spectroscopy with a microscope to provide high-resolution imaging and analysis of samples at the micron and sub-micron scale.

The LabRAM Soleil Raman Microscope uses a laser to excite a sample and measures the resulting Raman scattering to provide information about the sample's molecular composition and structure. Typically, a sample is illuminated with a laser beam. Electromagnetic radiation from the illuminated spot is collected with a lens and sent through a monochromator. Elastic scattered radiation at the wavelength corresponding to the laser line (Rayleigh scattering) is filtered out by a filter, while the rest of the collected light is dispersed onto a detector. It can be used to analyze a wide range of materials:

  • Biological samples
  • (Multiplayer) Polymers
  • Nanomaterials
  • 2D materials
  • Confocal 3D imaging of an inclusion.
