Brewster angle

By placing these windows in a plane set at the Brewster angle with respect to the Ught beam, maximum transmission is assured (minimum reflection). The above considerations regarding polarization of refracted and reflected beams must be modified for nontransparent media such as metals, for which there is little polarization of a reflected beam.

It was estabhshed ia 1945 that monolayers of saturated fatty acids have quite compHcated phase diagrams (13). However, the observation of the different phases has become possible only much more recendy owiag to improvements ia experimental optical techniques such as duorescence, polarized duorescence, and Brewster angle microscopies, and x-ray methods usiag synchrotron radiation, etc. Thus, it has become well accepted that Hpid monolayer stmctures are not merely soHd, Hquid expanded, Hquid condensed, etc, but that a faidy large number of phases and mesophases exist, as a variety of phase transitions between them (14,15). 

The relative slopes of tanT (maximum or minimum). A, and reflectivity for the parallel component depend on the position relative to the Brewster angle (greater or lower). Thicker films on both types of substrate lead to dominant interferences.

Brewster-angle microscopy dispensed with the need for a probe molecule [41,42], Brewster-angle microscopy is based solely on the reflectivity properties of p-polarized light. The reflectance of p-polarized light at the water-air interface vanishes at 53.1° (using refractive indices at 20°C) if the interface is perfectly sharp in reality there is a deep minimum near zero. The presence of a monolayer gives an intervening layer of different re-...

Collapsing and nucleation processes of a stearic acid monolayer have been also studied on the different aqueous subphases by a Brewster angle microscope [15]. Both of the temperature and the pH value of the aqueous subphase can influence the nucleation process and produce very different collapsing patterns.
