REFLECTOMETRY AT THE BREWSTER-ANGLE AND BREWSTER-ANGLE MICROSCOPY AT THE AIR-WATER-INTERFACE

No reflection occurs if a p-polarized light beam is incident on a water subphase under the Brewster angle. Formation of a monolayer at this air-water interface leads to a measurable reflectivity depending on various film properties. A microscope based on this principle had been constructed. This paper gives examples of the potential of reflectometry and microscopy at the Brewster angle.
