Precision positioning for microscopy, photonics, semiconductor, optics alignment, and advanced automation
SHREWSBURY, Mass., Jan. 14, 2026 /PRNewswire/ -- PI (Physik Instrumente), a global leader in precision motion control and nanopositioning systems, is expanding its portfolio of direct-drive vertical translation stages with the V-571.Z family. Featuring a user-adjustable magnetic counterbalance, the V-571.Z direct-drive vertical translation stages are designed for demanding vertical positioning tasks requiring high accuracy, dynamic response, and long service life. The V-571.Z expands PI's precision motion portfolio for photonics, semiconductor, optical alignment, and metrology applications.
The V-571.Z Z-stages feature a direct-drive, non-cogging linear motor that delivers friction-free motion and dynamic performance in a compact platform. The integrated, user-adjustable magnetic counterbalance ensures minimal holding current on the motor when operating vertically, enabling efficient, high-acceleration motion without compromise.
Key Features of the V-571.Z Vertical Translation Stage
Even in its compact 95 mm body width, the V-571 design achieves superior travel accuracy, flatness, and guiding performance compared to many larger positioning stages, making it well suited for vertical focusing, scanning, measuring, imaging, and alignment tasks. Both incremental and absolute encoder options are available; models equipped with absolute encoders provide 1 nm resolution and eliminate the need for homing at startup, improving operational efficiency and safety.
The stage also benefits from ultra-precision cross-roller bearings that deliver smooth, stiff motion with low maintenance over the life of the system. When integrated into multi-axis configurations with linear V-571 stages for horizontal use, the V-571 series supports seamless XY and XYZ motion solutions tailored to production and research environments.
"Vertical nanopositioning with dynamic performance and minimal motor load has long been a challenge in high-precision automation," said Matt Reck, Managing Director Operations at PI USA. The V-571 Z stage answers this need with a compact form, advanced motion technology, and flexible encoder options tailored for today's photonics and semiconductor workflows."
Alternative Counterbalance Solutions
While PI also offers pneumatic and mechanical counterbalance solutions, the adjustable magnetic counterbalance principle provides advantages such as simplicity, flexibility, and compactness over the above-mentioned alternative solutions.
The V-571 Z stage is available now through PI's global sales channels and regional offices. See it live at Photonics West next week, booth #3517!
