A polarizer only passes the light-wave component aligned with its axis. Malus's law says the transmitted intensity is I₀·cos²θ, where θ is the angle between successive filters. Two crossed polarizers block everything — but slip a third at 45° between them and light reappears, a striking quantum-like result of projection.

Governing equation

I = I_{0} cos^{2} θ, θ = 4 5^{\circ} \Rightarrow I \approx 12.5% I_{0}

Reading this result: Each filter projects the beam onto its axis, multiplying intensity by cos² of the step angle; after this chain about 13% remains.

About this simulation

The full Polarization tool models a fiber sensor with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
