The F-141 is a compact, multi-axis precision alignment system designed for fast photonics array and fiber optics alignment, featuring 2 to 6 degrees of freedom with 40 mm XYZ travel and 12° Theta-Y rotation. The 6-axis variant includes motorized Theta-X/Z rotation with ±4° travel and 0.02 µrad microstep resolution. It uses three V-141 three-phase motor-driven crossed roller bearing stages in an XY+Z stack with a flexure-based voice-coil rotary stage, optimized for minimal lever arm and high stiffness. The system integrates a proprietary PILightning algorithm for industry-leading alignment speed and an ACS EtherCAT® controller with onboard machine learning for rapid signal analysis. Direct drive motors and optical encoders enable high-dynamics scanning with repeatable positioning. Optional motorized rotation and embedded alignment routines support automated PIC test and silicon photonics assembly.
The F-141 is a cost-optimized multi-axis precision alignment system designed for fast and accurate motion in X, Y, Z & Theta-Y directions. It consists of three V-141.040 three-phase motor-driven, crossed roller bearing stages stacked in a XY+Z arrangement with a custom voice-coil motor-driven, flexure-based rotary stage mounted to the front of the Z stage. The Z-stage is equipped with a pneumatic counterbalance and brake.
The combination of ultra-precision crossed roller bearings and flexures plus compact size offers high performance motion with excellent stiffness and positioning stability. The compact geometry minimizes angular errors for highly repeatable positioning at the probe tip. Direct drive motors and optical encoders enable this system to perform fast scanning motion for alignment over short and long travel ranges. An optional manually adjustable pitch/yaw base for the system allows for full adjustment in all six degrees of freedom. Other configurations are available for applications with different optical axis orientations.
