Raman spectroscopy

Raman spectroscopy

Raman spectroscopy is a molecular spectroscopic technique that relies on inelastic scattering of monochromatic light in molecular structures. The incident laser light changes the excitation states of the molecules, and during this process, the molecules will emit light at higher and/or lower wavelengths relative to the excitation wavelength (called Stokes or Anti-Stokes shifts). Each material has its own specific Raman spectrum. Raman scattering can, therefore, be used to identify and quantify the presence and composition of various substances.

The highest efficiency Raman spectrometers

Ibsen’s transmission grating based spectrometers are ideally suited for Raman spectroscopy due to the following benefits:

  • Nearly 100% polarization independent efficiency (optical throughput)

  • Integration with both cooled and non-cooled CCD detectors and cameras

  • Robustness for portability, usage, or challenging industrial environments

  • Low temperature dependence

  • Error-free imaging of linear fiber array in the image plane

  • Compact size
