Piezo Positioner Resolution

The term position noise or resolution is a key measurement associated with piezo stages. This measurement is a determining factor of how small a step size can be achieved (the other being controller resolution). Please note that in a piezo flexure stage the limiting factors are different than other piezo motors or stick slip piezo […]

Piezo Flexure Stage Footprint

The size and shape of a stage is very important when choosing the right system for your application.  Consider how the stage will be integrated in the system. Some stages are designed for certain functions like moving a microscope objective while others are designed solely for AFM applications.  Be sure to look at the physical […]

Piezo Stage Axis of Motion

Axis of motion and stage design are important requirements when choosing a system that fits a certain application.  First, consider what planes of movement are most important. Nanopositioning systems have X, Z, XY, XYZ, and tip/tilt motion associated.  Next, determine what travel range (see previous post for more on Travel Range) is necessary for each axis […]

Piezo Stage Travel Range

Travel range is the maximum distance a piezo stage can move in a single axis. Current flexure stage design can provide travel ranges of up to 2mm in a single plane and 10s of mradians of tip/tilt motion. There are often two specifications you will see when comparing stages: open-loop and closed-loop range. Open-loop range […]

Things to Consider When Acquiring a Nanopositioning System

There are many factors to consider when looking for nanopositioning piezo stages. The following series of articles will help explain some items that are important when looking at different stages and systems. Those who are new to the world of nanopositioning, please contact us with any additional questions. There are different types of “nanopositioners” on […]
