April 16, 2009 - Aerotech NanoTranslation (ANT95-L, ANT95-L-H) cross-roller bearing stages combine high speed, accuracy, resolution, repeatability, and reliability into a compact package. As an evolution of the popular ANT stage family, these linear stages exhibit enhanced motion performance such as 5 g acceleration, 500 mm/s velocity, enhanced load capacity, and standardized, universal base mounting patterns that allow the use of this flexible stage family in a wide range of configurations.
Noncontact Direct-Drive
ANT95-L stages utilize advanced direct-drive technology, pioneered by Aerotech, to achieve the highest level of positioning performance with resolution of 5 nm, repeatability of 50 nm, and accuracy of 250 nm. Aerotech direct-drive technology is non-cogging, noncontact, high speed, high resolution, and high accuracy, and the use of anti-creep cross-roller bearings allows ultra-precision (5 nm) incremental moves to be accomplished reliably and repeatably. This unique drive and bearing combination, packaged in an extremely small-profile and footprint, offers tangible advantages in applications such as high-precision positioning, disk-drive fabrication, fiber alignment, optical delay element actuation, sensor testing, and scanning processes that demand smooth and precise motion.
Flexible System Design
The ANT95-L family has universal mounting and tabletop patterns that allow for easy system integration. Two, three, or more axes can be easily combined for flexible system designs and multi-axis configurations.
System Characteristics
Outstanding accuracy, position repeatability, and in-position stability require high system resolution. The ANT95-L industry-leading 5 nm minimum incremental step size provides this high level of performance. Excellent in-position stability assisted by high-quality, anti-creep cross-roller bearings enables virtually maintenance-free operation over the life of the product. Aerotech’s direct-drive technology has no hysteresis or backlash, enabling accurate and repeatable nanometer-scale motion.
System Control
To get the most out of your ANT95-L, Aerotech produces high performance, single- and multi-axis motion controllers that excel in any application. The Automation 3200, Ensemble, and Soloist controllers are a perfect complement to a high-performance stage.
