Bammer, F. (2024). Ellipsometric Measurements on Oil-layers on Technical Surfaces. In K. Hingerl (Ed.), OSI 14 : The 14th International Conference on Optics of Surfaces and Interfaces (pp. 10–10).
We examine the usefulness of IR-ellipsometry for the measurement of the thickness of oil layers on metals, or more generally, of dielectric layers on metallic substrates. IR-ellipsometry may offer in inline applications like rolling or deep-drawing more robustness than the currently
used methods, based on IR-spectroscopy or fluorescence, which are too dependent on the type of substrate and/or the type of oil.
