The liquid crystal polarization rotator (LPR) from Meadowlark Optics continuously rotates the polarization orientation of a monochromatic, linearly polarized input beam. Our LPR consists of a compensated variable liquid crystal retarder in combination with a zero-order polymer quarter-wave retarder. The fast axis of the variable liquid crystal retarder is aligned at a 45° angle to the slow axis of the quarter-wave retarder, and the linearly polarized input beam must be parallel to the slow axis of the quarter-wave retarder. The polarization rotation is achieved by electrically controlling the delay of the variable liquid crystal retarder, thus avoiding any mechanical movement.
Our variable optics stand for precision and reliability. If you have any further questions about the systems, please feel free to send us a non-binding inquiry. Further information about the products and all technical data sheets for each variant can be found here: meadowlark.com.
