FTIR spectroscopy is a valuable method for the analysis of coatings. It allows to identify the chemical identity of the used material and to determine the thickness of coating layers. The method is nondestructive, fast, and precise. Bruker’s ALPHA is an easy to use system for routine quality control and identification of surface coatings. Coatings on small and unevenly shaped samples can be analyzed using the fully automated FTIR microscope LUMOS. It allows to monitor the homogeneity of coating with high spatial resolution and to identify small defects and contaminations for effective failure analysis.
