Linear Stage

Photonics Spectra
Jan 2026The V-573 from PI (Physik Instrumente) is a series of linear positioning stages with excellent guiding precision and frictionless 3-phase linear motors. The stages have 80-nm bidirectional repeatability, 1g acceleration, and 500 mm/s velocity for precision and speed in demanding production environments. The stages are designed for XY configurations and integrates seamlessly with PI’s ACS-based EtherCAT motion controllers. The stages feature straightness and flatness values as low as 1 µm. Crossed roller bearings ensure high stiffness, smooth running, and extended lifetime. Their line-contact design minimizes friction, improves accuracy, and supports higher loads, with an anti-creep mechanism for reliability. Direct force transmission together with direct-measuring linear encoders eliminates backlash and play while improving accuracy and bidirectional repeatability.More products
