Switchable Polarization Rotator
from Arcoptix S.A

Liquid Crystal twisted nematic polarization rotator (TN cell) is very useful when one wants to rotate the orientation of a linear polarization by a fix amount of typically 45 ° or 90 °. When light is traversing LC twisted nematic cell its polarization follows the rotation of the molecules... [See More]
