Trajectory Generation with Nanopositioning Systems
Trajectory Generation is the latest feature on nPoint’s nPControl software environment for the LC.400 Series Nanopositioning Controllers. The trajectory generation interface allows a user to scan through up to 500 position coordinates, with velocity and dwell time specified individually for each positioning event. These coordinates are downloaded to the controller...

Nanopositioning Stage Operating Conditions
Consideration of the environmental conditions where a nanopositioning system will operate is important to achieve the desired result for a given application. These conditions include: Piezo stages can be made from various materials such as invar, stainless steel, titanium and aluminum. Each has advantages; however it is often important to...
Resonance Frequency of a Piezo Flexure Stage
The first (or lowest) resonance frequency per axis is typically specified for a nanopositioner. The resonance frequency could be of the mode along the motion axis or along other axes including rotation and other complex modes. In general, the higher the resonance frequency of a system, the higher the stability...
