BARRINGTON, N.J., Oct. 28, 2015 — A polarimeter from Meadowlark Optics Inc. features computer control for manufacturing and laboratory applications. The device accurately measures Stokes parameters 10 times per second, quantifies the state of polarization, and graphically displays the Poincaré sphere, polarization ellipse or a running chart. A lack of moving parts ensures vibration-free operation. The polarimeter uses liquid crystal variable retarders to ensure compatibility with a variety of stability-sensitive applications. Edmund Optics Inc. is the distributor.
