Polarization Apparatus

Polarization Apparatus

<< >>
Brewster's Angle, named for the Scottish physicist, David Brewster, is the angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent surface. This device determines Brewster's angle for different subtances. The U.S. Military Academy purchased it in 1829, probably from Lerebours in Paris.
