Variable Wave PlatesAll of the wave plates featured here allow the retardance to be varied. For liquid crystal retarders and pockels cells, the retardance is tuned over a specified range by changing the drive voltage. The Soleil-Babinet compensator achieves variability by using a micrometer to change the position of a long birefringent wedge with respect to a fixed wedge. We also offer an Liquid Crystal Polarization Rotator that uses a liquid crystal retarder in combination with a quartz quarter-wave plate to provide continuous rotation of a linear input polarization.
