Introduction
Aerotech’s ANT series stages are the world’s first nanometer-level positioning systems with greater than 25 mm travel. Designed for vertical axis applications, the ANT130LZS series crossed-roller stages are the best-in-class in combining speed, resolution, accuracy, repeatability, reliability, and size, and are offered in two accuracy grades.
The ANT130LZS stages use a nearly frictionless dual-counterbalance mechanism to maintain performance levels while minimizing motor heating. The counterbalance is user adjustable from 0 to 14 kg. The dual-counterbalance design minimizes overall stage height and prevents off-axis moments that are applied by the counterbalance design that adversely affect straightness and angular errors. The result is positioning and geometric performance nearly equivalent to a non-counterbalanced ANT stage.
Noncontact Direct-Drive
Only noncontact direct-drive technology offers the robust, accurate, and high-speed positioning necessary for mass production of precision devices. ANT130LZS stages utilize advanced direct-drive technology pioneered by Aerotech to achieve the highest level of performance for 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 ANT130LZS 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 small minimum incremental motion (mechanical resolution). The ANT130LZS stage’s industry-leading 2 nm minimum incremental step size enables this high level of performance. Excellent in-position stability is assisted by high-quality, anti-creep, crossed-roller bearings. The stage offers 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.
