OZ Optics offers convenient and economical motorized rotators, allowing precise management of polarization states in single or multi-stage optical systems with multiple paths. These rotators facilitate controlled and synchronized rotations, either sequentially or concurrently, via a single compact control unit. Integrated into a palm-sized enclosure alongside a processor and touch screen, the control unit governs multiple motors through an intuitive graphical user interface (GUI). Plug-and-play functionality is achieved, accommodating diverse system complexities for demanding applications.

The input and output ports of each stage support various configurations, including fiber-connector receptacles, pinholes for free-space applications, or pigtailed with single mode, polarization maintaining, or multimode fibers. Within the rotators, polarization state manipulation is accomplished with precision using rotating waveplates, polarizer plates, polarizer prisms, or polarization beam splitters, achieving sub-degree resolution.

The offerings include high-power optics and connectorized fibers catering to a broad spectrum of operating wavelengths. The software and GUI are customizable upon request, and users can access a Python library for additional flexibility.

Key features:

• Precision rotation of half wave plates, quarter wave plates and polarizers to manipulate polarization
• Built-in encoder for closed loop operation
• Compact handheld plug-and-play device with touch screen control or with a computer via a USB port
• User-friendly software with an intuitive GUIs
• Can be pigtailed with single-mode, polarization maintaining or multimode fibers
• Customizable software and GUI upon request
• Interchangeable optics, holders and receptacles

Applications: Automation of multi-polarization state analysis, quantum state tomography, polarization calibration, polarization state analyzer and controller, polarized fiber optic source, polarization extinction ratio controller and PM fiber axes conversion, optical Interferometric systems, laser to fiber coupling and coherent detection
