Infrared and Raman microscopy have become important components to a complete forensic investigation. The highly specific nature of infrared and Raman chemical analysis greatly facilitates the identification of unknown compounds. In this webinar, we will discuss the superior results that using these two techniques can produce for analysis of drug and trace identifiers, paint chips, pigments, and other inorganic based samples during forensic investigations.
During this webinar we will also cover uses of optical microscopy, which can be another important compliment to the spectroscopic analysis. Optical analysis provides the physical properties of the samples in question, such as color, shape, and morphology. Contrast enhancement tools, such as the aperture stop in the Kohler illumination beam path, visible polarizers, darkfield illumination, and fluorescence illumination, are used to facilitate the visualization and characterization of fibers, multilayer laminates, paint chips, gun shot residues, and other evidence.
