The H-900KSCO is a reference-class, 6-axis positioning system designed for dynamic motion in all degrees of freedom (X, Y, Z, pitch, roll, yaw). This compact hexapod provides linear travel ranges up to 200 mm and rotation to 66 degrees for applications such as motion simulation, industrial production, precision machining, automotive industry, and stabilization of motion on moving vehicles and vessels.
PI presents the new V-52X family of compact high-speed, voice-coil linear motor stages as part of its PIMag series. These stages are equipped with a linear encoder for direct position measurement and choice of cable exit direction, and achieve significantly higher dynamics than stepper or servo motor-driven positioners. They are ideal for industry and research scanning applications such as biotechnology, laser beam control, optics scanning, lens testing, and fiber optics.
PI (Physik Instrumente) offers several controller and Z-stage value packages designed to deliver higher performance and lower costs for microscopy, metrology, 3D imaging, screening, autofocus systems, surface analysis, and wafer inspection applications. The systems feature 100, 250, and 400 μm travel ranges, and are comprised of a PIFOC® high performance fast piezo focus mechanism, a compact digital servo controller, a comprehensive software package, and an M32 threaded QuickLock insert.
The PIglide MB is an air bearing stage that is linear servo motor driven, and features fully preloaded air bearings and an integral optical linear encoder. The stage has a non-contact design for frictionless, high-quality performance within a miniature package.

A linear encoder can be used to significantly improve the accuracy and repeatability of stepper or servo-motor positioning stages, but even the high-end linear encoders have linearity errors. To reduce these errors, a laser interferometer measures them and uses a motion controller with the capability to store a dynamic error map.
