As with other spectroscopic techniques, Raman spectroscopy detects certain interactions of light with matter. In particular, this technique exploits the existence of Stokes and Anti-Stokes scattering to examine molecular structure.

WebA Raman spectrum is a powerful tool for materials research, the development of new pharmaceuticals and wherever chemical microanalyses down to the nanometer range is required. That's right, Raman can analyze samples down to 0.5 µm (500 nm). All you need is a confocal Raman microscope. WebHere we present a macroscopic line scanning Raman imaging system that has been modified to ensure suitability for intraoperative use. The imaging system has a field of view of 1 × 1 cm 2 and acquires Raman fingerprint images of 40 × 42 pixels, typically in less than 5 minutes. The system is mounted on a mobile cart, it is equiped with a ... mmcf of natural gas
