Piezo Stage Load vs. Settling Time

To maximize the capabilities of piezo stages, it is important to understand how different factors contribute to the performance of the system. For many applications, the resonant frequency and settling time of a stage are of primary interest. In this blogpost we explore how the resonant frequency and settling time are affected by the load […]

How does the step response specification relate to scanning speed?

A nanopositioner with a high resonant frequency will have a fast step response specification. A nanopositioner with a fast step response specification allows the user to increase the bandwidth of the control loop. A high bandwidth control loop reduces phase delay, which in turn allows the user to scan at an increased rate. Phase delay […]
