Key Features
The controller of the Polarimeter PMI-2000 is integrated into the optical head. Temperature control and Stokes vector calculation are autonomously completed server-side in the Controller. This reduces the data volume of USB calls from PC to Controller.
The Stokes parameters comprise a four-component vector that completely characterizes the polarization of a light beam. The components of the Stokes vector are simple combinations of the intensity outputs from linear polarizers or circular polarizers.
The PolarVIEW software is a user-friendly interface which displays polarization data and allows the user to perform various operations:
