Simulate the polarization of a laser beam.
Have you ever wondered what would happen if you passed a linearly polarized beam through a quarter-wave plate at 46 degrees rather than 45 degrees relative to the fast axis of a quarter-wave plate? Who am I kidding, of course you have! This library lets you pass a beam through several optical elements and see what comes out the other side.

Polarization simulations using Jones calculus.
