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]

Dual Wavelength Waveplate -- W-HPD212
from Ross Optical Industries

The low (multiple) order waveplate is designed to give a retardance of several full waves, plus the desired fraction. This results in a single, physically robust component with desired performance. However, even small changes in wavelength or temperature will result in significant changes in the... [See More]
