Thin film Polarizer

JH Optek thin film  polarizers based on a coating made up of particular birefringent  materials having polarizing properties while the coating is designed  under Brewster angle.

Brewster Angle: For light  incident on a plane boundary between two regions having different  refractive indices, the angle of incidence at which the reflectance is  zero for light that has its electrical field vector in the plane defined  by the direction of propagation and the normal to the surface. For  propagation from medium 1 to medium 2, Brewster's angle is given as  arctan (n2/n1).
