"WebHow does ellipsometry work? Ellipsometry relies upon the measurement of the polarization state of a light beam, where light with a known polarization is generated and directed at the sample substrate, see Figure 1. The light may be transmitted through the sample or reflected off the sample. For the combined ellipsometry and QCM-D application, " - How ellipsometry works
