Piezo Positioners, Nano Positioning

  • Linear Precision Piezo Stages
  • Rotary Precision Piezo Stages
These compact precision piezo positioners provide very high position resolution in a small package. PI miCos motorized precision piezo stages employ different types of piezo motors (stick-slip motors, ultrasonic motors and "piezo grabber" type motors) based on size and performance requirements. Rotary and linear stages are available. These types of piezo positioners provide long travel ranges in the multi-millimeter range up to 1" and are guided by precision cross roller bearings or ball bearings. High-resolution optical incremental encoders provide position feedback for closed-loop control.

Even higher accuracy is achieved by frictionless precision piezo-flexure guided positioners with capacitive position feedback. These types of stages provide shorter travel ranges but repeatable sub-nanometer step-sizes, very high dynamics (to sub-millisecond response times, and scanning rates of 100's of Hz), as well as life times of up to 100 billion cycles.
