Expanded capabilities for through package identification using 785 nm and 1064 nm excitation Raman
Raman spectroscopy is a form of molecular spectroscopy that gives specific molecular information of materials. Raman is used widely for rapid, non- destructive, non-invasive identification testing in chemical, material, pharmaceutical and biomedical research, in medical diagnostics, and increasingly by law enforcement. A limitation of Raman spectroscopy is that samples can only be measured directly, or through transparent containers.
See through Raman Spectroscopy (STRaman™) is a newly developed technology that expands the capability of Raman spectroscopy to measure samples beneath diffusely scattering packaging material. Conventional Raman typically has a very small sampling area with a high power density at the laser focal point on the sample, which means that only a limited portion of a sample is measured, and samples may heat or burn. The ST technology has been designed to overcome these issues.
