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. The ANT95-L is offered in both 25 mm and 50 mm travels.
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 award-winning, 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 your high-performance stage.
