THz-Raman® Spectroscopy Benchtop Module

Ondax’s patented THz-Raman® Spectroscopy Modules extend the range of traditional Raman spectroscopy into the terahertz/low-frequency regime, 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 characterization.

The TR-BENCH is configured for benchtop use and offers a range of interchangeable sample interface accessories holder for fast, easy measurements, including a convenient vial/tablet holder and a steerable non-contact optic (see options below). The system also comes with a standard cage mounting plate (centered on the collimated output beam) to allow for customized collection optics or easy integration into a customized system. Options include circular polarization or a dual-port/dual polarization output for simultaneous measurement of both S and P polarizations.
