Linear Motor Stage Brings Nanometer Accuracy to Two-Axis Applications
Tue, 08/18/2009 - 12:05pm
Aerotech NanoTranslation (ANT95-XY, ANT95-XY-H) cross-roller-bearing, linear motor, dual-axis stages are the newest in the evolution of ANT series stages. The ANT95-XY and ANT95-XY-H are three-piece designs that allow travel in two dimensions (X and Y). The sleek design provides a profile of only 60 mm and a compact footprint. The stage comes with proprietary direct-drive motor technology, noncontact linear encoders, limits, an integrated cable management system, and two grades of accuracy.The ANT95-XY design allows optimal orthogonality, straightness, and flatness, resulting in a stage with exceptional geometrical tolerances. Aerotech’s direct-drive technology has no hysteresis or backlash, enabling 5 resolution, 50 repeatability, and 250 nm accuracy in both the X and Y dimensions. Both travel options (25 x 25 or 50 x 50 mm) come with the 60 mm profile height.
