Made of metal, offers much better mechanical stability and reliability than plastic type. The 3 loops are small, see photos below. New released products, we ordered directly from manufacturer.

The mechanical polarization controller provides complete Poincare sphere coverage by adjusting the angles of the user friendly paddles. The design utilizes three wave plates with fixed retardation and variable orientation angles to control the State of Polarization. The flexibility of the paddle design allows you to install a variety of fibers for use at different wavelengths. Additional options including integrated polarizers are available.

These devices can be tailored to meet most application requirements Please contact our technical design team to discuss specific requirements.

The Polarization controller unit is deigned to accept bare fiber, 900um loose tube fiber.
