    • Customization
      Customization
      PI is at home wherever unconventional solutions are required. This is no longer the case only in research areas. Today, nanotechnology is also present in standardized industrial processes.
    • Piezo nanopositioning tables
      Piezo nanopositioning tables
      Piezo positioning tables with solid-state guidance from PI combine sub-nanometer resolution and guidance accuracy with minimal crosstalk.
    • Miniature tables
      Miniature tables and small manipulators are an essential part of mobile measurement technology and medical devices, both in industrial automation and in research, also, for example, in UHV or non-magnetic environments.
      • Miniature linear tables
        For positioning tasks with limited installation space, miniaturized table tables are an essential element. Solutions with piezo motors such as Q-Motion®, PILine® and PiezoWalk® enable particularly compact solutions thanks to their direct drive principle.
      • Miniature rotary stages
        The compact rotary stages can be used in optical applications, where they are e.g. B. Position filters reliably and with excellent repeatability. Rotary tables can be flexibly integrated in multi-axis combinations and can be mounted on suitable linear tables without an adapter.
      • Miniature hexapods
        The most compact products for movement with 6 degrees of freedom are based on Q-Motion® piezo motor tables. But only hand-sized hexapods with brushless DC motors (BLDC) are available. Classic parallel kinematic hexapod design results in the most uniform possible performance in the axes. For long linear travel ranges, a design with a low overall height may be better.
    • Linear tables
      PI offers a broad portfolio of motorized linear tables for high-precision industrial applications such as the semiconductor and photonics industries, as well as for high-class research. There are vacuum versions for a large number of different models. Multi-axis combinations can be realized with the help of adapter brackets, or more compact with suitable lifting tables and rotation tables.
    • Linear actuators
      The wide range of technologies enables the optimal choice for almost every area of ​​application: Highly stable “set-and-forget” continuous applications benefit from the specific properties of piezo motors, even in a vacuum or non-magnetic environment. DC and stepper motor solutions are widely used in both industry and research and are known to be reliable.
    • Rotary tables
      The requirements for rotary positioning are broad in terms of payloads, sizes and accuracy. PI offers tables with all available drive technologies and guide mechanisms.
    • Cross tables
      Stability, precision and dynamics are key features in the areas of application of the PI cross tables. These properties form the basis for high throughput rates and reliable operation. Industrial production and inspection benefit from the use of high-load cross tables and planar scanners from PI.
    • Hexapods
      Hexapods offer six degrees of freedom of movement in the most compact space. For industrial applications, there are combinations of absolute measuring position sensors, suitable software and motion controllers with which even complex motion profiles can be conveniently commanded.
    • High-precision motion systems for automation
      High-precision motion systems for automation
      Highly precise, complex motion and positioning solutions require precision components, stable control and a lot of experience in engineering as the essential fundamentals. PI is a provider of technologically sophisticated drive components or high-precision positioners and offers customized solutions for integration.
    • Fast multi-channel fiber positioning systems
      Fast multi-channel fiber positioning systems
      Piezo scanners take on the fast, continuous scanning tasks where durability, dynamics and precision are important. The larger travel ranges are implemented using XYZ combinations or 6-axis hexapods. Thanks to the integrated routines, it is possible to carry out single-axis alignments up to complex, multi-axis fiber array positioning within a very short time.
