Forensic Investigations using Confocal Raman Imaging

Introduction
Crucial tasks in forensics include the microscopic analysis of very small objects in order to accurately verify the source of specific compounds of such sample, or to compare the characteristics of several samples. Confocal Raman Imaging is a very effective tool for such analysis as it provides information on the chemical composition as well as the spatial distribution of the components. The samples typically do not require specific sample preparation and remain unaltered for further investigations with other methods since Raman Imaging is a non-destructive, non-contact and non-contaminating analysis technique.
