    Oz Optics handy and cost-effective motorized rotators enable precise control of the polarization states of a single optical stage or multi-stage system with multiple optical paths. These rotators can be controlled and synchronized to perform precise rotations sequentially or in parallel using a single compact control unit. The control unit is incorporated along with a processor and touch screen in a palm-sized enclosure to control multiple motors via an intuitive graphical user interface (GUI)> Plug-and-play features are realized and enabled via a customizable GUI regardless of the system complexity for demanding applications.

    The input and output ports of a given stage can be fiber-connector receptacles, pinholes for free-space applications, or pigtailed with single mode, polarization maintaining or multimode fibers. The light beam is then directed through one or more rotators, where the polarization state (the electric field of the propagating wave) is manipulated via rotating waveplates, polarizer plates, polarizer prisms or polarization beam splitters with sub-degree resolution.

    High power optics, connectorized fibers for wide ranges of operating wavelengths are available.

    The software and the associated GUI can be modified upon request.
