Coherent THz-Raman Spectroscopy System

Advanced materials characterisation

Coherent

 

Coherent’s patented THz-Raman Spectroscopy Systems extend the range of traditional Raman spectroscopy into the terahertz/low-wave number, exploring the same range of energy transitions as terahertz spectroscopy – without limiting the ability to measure the fingerprint region. This region reveals a new “Structural Fingerprint” to complement the traditional “Chemical Fingerprint” of Raman, enabling simultaneous analysis of both molecular structure and chemical composition in one instrument for advanced materials characterisation.

 

Features:

  • Compact optical design with integrated high power single frequency laser source (Benchtop)
  • Robust, sealed optical design with broad operating temperature range for use in demanding environments (Probe)
  • Interchangeable sample interface - vial/tablet holder, steerable open beam, or contact probe tip
  • Fibre coupled output enables easy interface to a wide range of spectrometers
  • Fast collection of THz-Raman spectra from 5cm-1 to >3000cm-1 (150GHz to 90THz)
  • Simultaneous Stokes and anti-Stokes signals improve SNR while providing inherent calibration reference
  • Can be added on to an existing Raman system or spectrometer, or incorporated into a complete turnkey system
  • Available at 532nm, 785nm, 850nm, 976nm and 1064nm excitation wavelengths

Clear real-time differentiation of structural attributes of the material enables clear identification and analysis of polymorphs, raw material sources, defects and contamination, crystal formation, phase monitoring, and synthesis methods. Real-time, simultaneous measurement of both composition and structural analysis eliminates the need for multiple samples and instruments, lowering capital, training, and maintenance costs.

 

The THz-Raman spectral region covers both Stokes and anti-Stokes signals from ±5cm-1 to 200cm-1, (or 150GHz to 6THz), which contain important structural information about the molecule or crystal lattice. This region reveals a new “structural fingerprint” to complement the traditional chemical fingerprint of Raman, enabling simultaneous analysis of both molecular structure and chemical composition in one instrument for advanced materials characterisation.
