These XY-Linear Stages are based on non-contacting linear motor direct drives. Linear motors are frictionless, wear free, and provide high acceleration and excellent velocity control over wide dynamic ranges. PI recommends ACS motion controllers that provide advanced features such as InputShaping to improve settling behavior and suppress unwanted resonances. Linear encoders with resolution to 1 nanometer are available.
The M-545 is a manual XY-stage for microscopy applications. It can be motorized by replacing the manual micrometers with motorized versions. The M-545 XY stage also combines with the P-545 XY and XYZ nanopositioning stages for scanning microscopy applications.
Piezo linear-motor driven XY-stages combine the advantages of piezoceramic properties with long linear travel ranges. Ultrasonic linear motors provide rapid step/settle performance and a wide dynamic range. At rest, the self-clamping properties automatically lock the platform, providing high stability without the need for driving current.
Air bearing XY-linear stages provide the highest geometric performance. These true planar XY positioning systems use one common base for both the X and Y axes avoiding flex and torsion common with stacked X-Y stages.
Flexure-guided, piezo-driven XY linear stages are used in nanopositioning and scanning applications with short travel ranges on the order of 100’s of microns. They provide excellent accuracy, dynamic properties, and geometric performance (straighness, flatness, etc) with resolution down to the sub-nanometer range.
