Keysight 11896A Polarization Controller

The Agilent 11896A Motorized Polarization Controller now with L-band capability provides a wide operating range (980 nm & 1250-1640 nm) for measuring optical components. The 11896A adjusts optical polarization and not power. Its optical fiber loop design provides all states of polarization with extremely small optical insertion-loss variations. This performance combination maximizes measurement accuracy for power-sensitive applications like polarization dependent loss and gain. This is because the uncertainty provided by the polarization controller is minimized.
