Coherent THz-Raman Spectroscopy System

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:

• Fully automated operation
• Collects both Stokes and anit-Stokes signals from -800 to +2800 cm^-1 with ~4 cm^-1 spectral resolution
• Configurable scanning patterns
• FloodLight Mode to enhance collection speed and averaging performance
• Intra-well mapping data collection
• Plate autofocusing system
• Automated calibration
• Polarised light detection
• SPC and ASCII file formats

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.
