In the field of forensic sciences, Raman spectroscopy is predominantly used for the unambiguous identification of unknown substances. Given that Raman is a non-destructive technique, it has the advantage of being able to identify trace amounts of substances without compromising the evidence in any way, even allowing identification to be performed through a glass or plastic container. The high sensitivity, confocal performance and imaging capabilities of the inVia Raman microscope are key requirements, where enforcement agencies require detailed information on materials to obtain a successful prosecution. Renishaw's Raman microscopes have gained international recognition for successfully completing difficult forensic investigations such as distinguishing active drug forms and cutting agents from illicit materials, and proving which ink was deposited first in 'crossed ink' document authentication cases.
