Our Polarimeter is a compact system with convenient computer control that accurately measures Stokes Parameters 10 times per second. It quantifies the State of Polarization (SOP) and graphically displays the Poincaré Sphere, Polarization Ellipse, or running chart. The Meadowlark Optics system contains no spinning waveplates, motors, or other moving parts to wear or cause vibrations. Patented algorithms provide high accuracy and calibration versatility.
