About M-686-XY Piezomotor Stages and Scanners
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 scaning stages; the low profile height of the M-686 (only 27 mm) provides for a very compact system.

Space Saving Piezo Motors
Compared to conventional motorized 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.

Combines with High-Resolution Scanning Microscopy Piezo Stages
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 6 Axes.

Closed-Loop Operation: Optimized for High Velocity and Rapid Step/Settling
The M-686 stages can be operated in closed-loop with the new C-866 piezo motor controller / driver. This highly specialized controller achieves very short settling times (millisecond range) and can handle speeds up to 400 mm/s.
