A-121 PIglide AT1 Linear Stage with Air Bearings

High Performance Small Footprint Nanopositioning Stage

A-121 PIglide AT1 Linear Stage with Air Bearings

Product Description Specifications Downloads Quote / Order

The stages in the PIglide are equipped with a servo drive linear motor with preloaded air bearings and integrated linear encoder. The combination of these noncontact components results in a frictionless motion platform that offers the highest performance, quality, and lifetime.

A high-force linear motor can drive the stage to top speed within a few milliseconds. The preloaded air bearing construction supports mounting in any orientation.

Encoder
PIglide filter and air preparation kits
Multi-axis motion controller and direct drives
XY setups and individual configurations
Cable track variations
Counterbalance options for vertical assembly
Base plates made of granite and systems for reducing vibration

PIglide positioning systems are ideally suited for many high-precision applications such as metrology, photonics, and precision scanning in semiconductor or flat panel display manufacturing.

Thanks to the friction-free motion, no particles are formed, which makes PIglide stages ideal for cleanroom applications.

⁽¹⁾ Dependent on the flatness of the surface, on which the stage is mounted.

⁽²⁾ Can be limited by the payload, controller or drive.

⁽³⁾ Assumes 4096x interpolation. Contact PI for the use of other factors.

⁽⁴⁾ Improved accuracy can be obtained with controller-based error compensation. The stage must be ordered with a controller from PI to reach these values. Accuracy values assume short duration and do not consider the long-term effects of thermal drift on the stage.

⁽⁵⁾ To protect the stage against damage, it is recommended to connect an air pressure sensor to the Motion-Stop input of the controller.

⁽⁶⁾ Assumes an air bearing operating pressure of 70 psi (480 kPa).
