Nano-Positioner Manufacturer Chooses ZYGO DMI System To Characterize Performance

This article tells the story of how Physik Instrumente (PI), a premier supplier of nano-positioners, needed to characterize and quantify the performance of their PICMAWalk positioner, and used ZYGO's ZMI™ Displacement Measuring Interferometer  to demonstrate their PICMAWalk positioner's capability to reliably and repeatably move in 0.5 nm steps using closed-loop control.
