Brewster Angle Calculator

Here is the Polarization by Reflection Calculator to calculate the Brewster's angle. Brewster's angle (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. This brewster angle calculator uses Brewster's Law of Polarization, which states that maximum polarization is achieved when refracted ray is at 90° with the reflected ray on a surface of a transparent medium.

Formula:

θpolarizing = arctan(nt/ni) Where, θpolarizing = Brewster Angle / Polarization Angle ni = Light from a Medium of Index nt = Light Incident upon a Medium of Index

Example:

Polarization by Reflection Calculation
Find Polarization Angle using the brewster's law of polarization, if the values of nt and ni are 10 and 20, then Brewster Angle = 10/20
= 63.43 degrees.
