Calculate polarization angle using this simple brewster angle calculation tool. In optics, Brewster 's angle (also known as the polarization angle) is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection. When unpolarized light is incident at this angle, the light that is reflected from the surface is therefore perfectly polarized.
Formula:
θb = tan-1(n2 / n1)
where,n1 - is the refractive index of the initial medium through which the light propagates
n2 - is the index of the other medium
θb - brewster's angle
