🕶️ Polarizer Bench: Malus Law, Three-Filter Paradox and Brewster-Angle Glare Lab

Rotate up to three polarising filters on an optical bench and watch the Stokes-Mueller maths: Malus' law, why a filter at 45 degrees between two crossed filters lets light through again, how cheap film leaks, and how a glass plate polarises reflected glare until Brewster's angle removes one polarisation entirely. Blender-modelled bench, live beam polarisation, graphs and two measured-versus-theory experiments.
