Polarization & Phase Control

High Precision No Drift Polarization Controller – Repeatable, USB

The POLU is a turn-key module, providing precise polarization control with three independently step-motor-driven rotatable waveplates, adaptable for both fiber-coupled and free-space applications across a wide range of operating wavelengths and high optical powers. The POLU is designed to convert incoming light with any polarization state into a specific polarization state on the Poincaré sphere, working together with a polarimeter. With a single or dual rotator configuration using polarizer plates, polarizer prisms, or polarization beam splitters, the POLU functions as a polarizer with sub-degree directional resolution. A high-precision driver with a built-in encoder allows adjustments with accuracy better than 0.03 degrees, managed through an intuitive GUI accessible via USB or RS232. This plug-and-play unit includes a wall-pluggable DC power supply.
