Enable 3rd polarizer
Malus's Law: I = I₀ · cos²θ
θ is the angle between the transmission axes of the two polarizers.
Brewster's angle θ_B = arctan(n₂/n₁). At this angle, reflected light is completely s-polarized (⊥).
Birefringent crystals split light into two orthogonally polarized beams with different speeds. Wave plates use this to control polarization state.
