Closed-Loop Fast Focusing Nanopositioning Drives: Voice-Coil or Piezo - Your Choice

Voice Coil Drives with Mechanical Bearings cannot achieve the straightness and geometric performance as a piezo-flexure guided mechanism. Piezo flexure mechanisms cannot provide the travel range of a voice-coil / cross-roller guided mechanism.

There is no one size fits all but either way you chose, you can get it from one source, with 50 years of nanopositioning experience built into each device.
