Deciding Between Open-Loop and Closed-Loop Piezo Stages

The term “closed-loop” in nanopositioning indicates that a sensor is used to monitor the position of the stage in real time. These readings feed back to the controller to provide error correction for the system. Closed-loop control ensures that the nanopositioner reaches the desired commanded position. nPoint uses interferometric calibration for each stage to confirm […]

Benefits of Piezo Flexure Stages

Flexure stages employ a flexure bearing mechanism as a foundation for motion control. A moving platform is connected to the static base of the stage by flexure hinges. The moving platform is driven by piezo actuators to achieve desired motion. Guiding motion is provided by the deformation of the flexure material. This linkage is virtually […]
