The ThorLabs PA Series Polarimeter is a versatile 'full polarimeter,' which utilizes the rotating quarter waveplate (QWP) technique to measure the state of polarization (SOP) and degree of polarization (DOP) of an incident beam. Both free space beams and connectorized fibers are supported. The SOP is displayed numerically as a normalized Stoked vector, and graphically as a vector on a unit Poincare sphere. The DOP measurements include the total DOP, the degree of linear polarization (DOLP) and the degree of circular polarization (DOCP).
