Confocal Raman Imaging – Depth Profiling of Polymer Films and Coatings

Coatings and films play an important role in many fields of application, such as drug delivery and food packaging, which makes an efficient technique for the investigation of these materials essential. In this application note from WITec Confocal Raman Microscopy is shown to be a powerful tool for non-destructively imaging the chemical composition of heterogeneous component within a film or coating.
