- Nanometer performance in a large travel format (35 and 60 mm)
- High resolution (2 nm), repeatability (75 nm) and accuracy (300 nm)
- In-position stability of <2 nm
- Anti-creep crossed-roller bearings
- High dynamic performance
Aerotech’s ANT series stages are the world’s first nanometer-level positioning systems with greater than 25 mm travel. The ANT130-L-Z and ANT130-L-Z-PLUS crossed-roller stages are the best-in-class in combining speed, accuracy, resolution, repeatability, reliability and size, and are offered in two accuracy grades. As an evolution of the ANT stage family, these linear stages exhibit enhanced motion performance over Aerotech’s first generation ANT series.
All of the original ANT series’ direct-drive advantages have been preserved in the ANT130-L-Z family. Only noncontact direct-drive technology offers the robust, accurate and high-speed positioning necessary for mass production of precision devices. ANT130-L-Z stages utilise advanced direct-drive technology pioneered by Aerotech to achieve the highest level of positioning performance for high-precision positioning, disk-drive fabrication, fibre alignment, optical delay element actuation, sensor testing and scanning processes that demand smooth and precise motion.
The ANT130-L-Z stages use a nearly frictionless counterbalance mechanism to maintain performance levels while minimizing motor heating. The counterbalance is user adjustable from 0 to 10 kg.
Flexible System Design
The ANT130-L-Z 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.
Outstanding accuracy, position repeatability and in-position stability require high system resolution. The ANT130-L-Z stage’s industry-leading 2 nm minimum incremental step size provides 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.

- Certified with each stage.
- In-Position Jitter listing is 3 sigma value.
- Axis orientation for on-axis loading is listed.
- Air supply must be clean, dry to 0°F dewpoint and filtered to 0.25 µm or better; recommend nitrogen at 99.9% purity. Supply pressure is determined by the amount of payload carried by the stage.
• Specifications are for single-axis systems measured 25 mm above the tabletop. Performance of combined multi-axis systems is payload and workpoint dependent. Consult factory for multi-axis or non-standard applications.
• -PLUS requires the use of an Aerotech controller.
