Piezomotor stages meet high-resolution needs

A PI (Physik Instrumente) product story

The low-profile M-686 open-frame xy piezomotor stages are mainly designed for automated-positioning applications in inspection and microscopy.

PI (Physik Instrumente) has released the new M-686 low-profile xy open-frame piezomotor stage with linear encoders.

The low-profile M-686 open-frame xy piezomotor stages are mainly designed for automated-positioning applications in inspection and microscopy.

For ultra-high resolution applications they can be combined with nanopositinng scanning stages; the low profile height of the M-686 (only 27mm) provides for a very compact system.

Compared to conventional motorised translation stages, the M-686 provides a lower profile and smaller footprint.

The compact PILine piezoelectric linear motors and high-resolution linear encoders make both the leadscrew / duct and flanged, bulky stepper motor employed in traditional stages obsolete.

In addition, the piezo motors are self locking at rest and hold the stage in a stable position.

For ultra-high resolution applications, a number of piezo-nanopositioning systems can be mounted in the xy motor stage.

They are available as fast, xy scanners (for fluorescence microscopy), as z positioners (3D imaging), or with up to six axes.

The M-686 stages can be operated in closed-loop with the new C-866 piezo motor controller / driver.

This highly specialised controller achieves very short settling times (millisecond range) and can handle speeds up to 400mm/s.
