  1. Piezo Components For Liquid Handling 9/5/2023

    Explore the versatile use of piezoelectric microfluidic devices in precise liquid handling for diverse applications including genomics, diagnostics, cytometry, and lab automation.

  2. How to Use Hexapod 6-DOF Motion And Positioning Systems 8/9/2023

    Discover the versatile uses of hexapod positioning systems (Stewart Platforms) for multi-axis positioning, motion simulation, and 6 degrees of freedom with adjustable pivot point.

  3. Laser Seam Welding Of Electronic Packages Using Galvo Scanners 7/18/2022

    In laser seam welding, agalvo scanner helps expand the laser source’s effective fine spot size to the seam width, lays a complex welding pattern over the motion path to create high-quality welds, increases throughput, and takes advantage of higher power laser sources.

  4. Fast Steering Mirrors (FSM) - Design, Performance, And Tuning Of Piezo-Based Mechanisms 6/7/2022

    In free space optical communication (FSO), large amounts of data are “beamed” between two points – on earth, on aircraft or between satellites in space. Fast steering mirrors (FSM) are one means to compensate for disturbances that could keep the laser beam from hitting its target receiver precisely. 

  5. Multi-Axis Stages: Why Custom Aligned, Tuned, Error-Corrected XYZ Assemblies Are Better 4/18/2022

    Multi-axis precision motion at the micron or sub-micron level is required in many industrial automation processes as well as in test and metrology applications. Users of such motion systems often ask: Should I just get the individual components and bolt them together myself, or rather specify a complete XYZ system, mounted, aligned, and tested by a specialist? The answer depends on expectations, performance requirements, and budget.

  6. Piezoelectric Positioning Equipment For Nanoscale Microscopy & Imaging 4/18/2022

    The compound microscope has quickly fallen behind alternative tools capable of performing high-precision materials characterization or insights into molecular activities on the nanoscale. PI offers a range of positioning equipment suitable for sub-nanometer resolution microscopy and interferometry. 

  7. How To Connect A Safety Light Barrier To A Hexapod System 11/19/2021

    This white paper from PI explains when it is useful and necessary to use a safety device, how a safety light barrier (or light curtain) works, how the risk assessment for hexapods is carried out, and how the safety device can quickly be integrated in the controller environment.

  8. What Is The Difference Between Parallel Positioners And Stacked Serial Kinematics? 9/27/2021

    When faced with a multi-axis motion application, many users stack motion stages, and in fact that is a fine approach for assemblies of just a few axes. But as applications become more complex, so do the equivalent stacks-of-stages, and very real and practical considerations begin to come into play.

  9. Hexapod FAQs 9/24/2021

    Hexapods provide motion in all 6 Degrees of Freedom, X,Y,Z, Pitch, Roll, Yaw.  6-DoF motion platforms and positioning systems are often referred to as Stewart Platforms.

  10. Piezo Controllers/Mechanisms: How To Select The Right Piezo Controller/Driver 8/23/2021

    When selecting a motion controller / driver for a piezo nanopositioning system, a number of questions need to be answered first.  Here’s a check list and an example that can help make the best choice.
