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, WebFigure 1: Characteristic components of an Imaging Ellipsometer. The basic geometry resembles the typical setup of any ellipsometer: A light source and polarization control are mounted on one “arm” of the instrument, providing a light beam that illuminates the sample at an oblique angle of incidence (AOI). The probing beam reflects from or ...
