Polarization & Phase Control
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.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
High Precision No Drift Polarization Controller – Repeatable, USB: Laboratory optical integration depends on preserving the optical budget through the complete path. The 1550nm, 1310nm, 1060nm, 980nm, 850nm, Special wavelength specification sets source and detector compatibility. The fiber/interface entry (SMF-28, Hi1060, SM980, SM850, 780HP, SM1950, Free Space, 50/125) must match the connected components.

Technical FAQ
Interface: USB · Input Fiber: SMF-28, Hi1060, SM980, SM850, 780HP, SM1950, Free Space, 50/125. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength: 1550nm, 1310nm, 1060nm, 980nm, 850nm, Special. Check the Polarization & Phase Control passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
