Thorlabs PA430 Free Space Polarimeter Set General Description: PA430 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 Stokes 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). Wavelength Range: 1100-1600 nm Accuracy D.O.P: ±1.00% @ Calibration Wavelength/±1.5% Over Operating Range Measurement Rate: 25Hz With Adjustable Display Update Rate The Thorlabs' Polarization Analyzer Software offers the user powerful features, and is compatible with Windows 3.1 and Windows 95/98 (preferred), The software offers:, Real-time graphical display of polarization vector, degree-of-polarization and ellipticity measurements., User-configured display options: sample rate, update rate, Stokes polarization vector tracer line with depth shading and tracer line strength, Numerical data pop-up windows showing raw voltages, normalized Stokes vectors, DOP, DOLP, DOCP, ellipticity and azimuth angle, a prescribed Calibration Algorithm, and a Manual Calibration mode in which the elements of the calibration matrix may be manually entered, Poincare sphere rotations and zoom, User configured data logging mode allows "raw" detector voltages and measured polarimetric parameters to be stored in a *.prn file format. |
