DSM’s nanopositioning piezoelectric ZSA-1000C stage features flexure-guided motion over a 1000 micron travel range for scanning, metrology, and inspection processes. The stage’s stable and stiff kinematic design promotes parallelism in the output motion with minimal pitch and yaw as well as dynamic responsiveness for excellent position stability and control.

Operation / Performance

The ZSA-1000C's structure easily accommodates the use of a variety of displacement sensors including capacitive probes (standard) for true nanopositioning motion control capability.

DSM's SA-500 servo amplifier provides stand alone closed-loop control with serial communication, analog or digital feedback, and digital I/O for additional control and communication capabilities.
