Description
The Brewster angle corresponds to the angle of incidence at which light of a certain polarization is not reflected. If one wishes to study a thin film located at the surface of a substance, it is useful to illuminate the sample at the Brewster angle, thus avoiding reflections from the substance. Brewster angle microscopy is particularly well suited to characterize air / water interfaces. It also enables one to characterize solid / air interfaces when the instrument is used in the ellipsometric imaging mode.
