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 ... WebEllipsometry is so called due to use of elliptically polarised light (two light beams that are out of phase) to analyse samples. It is an optical, non-invasive and non-destructive …
