Nano-Focus Systems Based on Piezo Drives
|
Piezo based nanopositioning focus drives / objective positioners are designed for fast motion and high resolution over travel ranges typically from 100 µm to 500 µm. Their stiff piezo actuation system enables fast scanning rates and step and settle times in the low millisecond range.
A new version with a piezo walk motor is now also available for long travel ranges to 2 mm.
