Les applications des couches minces en polarimétrie

F. Abelès


Abstract
A thin transparent film on glass is used in order to get reflecting or transmitting polarizers. The former case is the analogous of Brewster's reflection. One can get a very luminous and almost achromatic polarizer by using a high index film. In the later case, we use a device similar to the pile of plates. Two plates of glass covered with titanium dioxyde on both sides give a degree of polarization of 99,7 per 100.
