ant95-3-vAerotech’s ANT series stages are the world’s first nanometer-level positioning systems with multi-millimeter travel. The ANT-V and ANT-V-PLUS are linear-motor-driven wedge-style vertical lift stages. The stages are designed to be seamlessly integrated with other stages in the ANT family for superior multi-axis performance and are offered in two accuracy grades.

  • High resolution
  • Anti-creep crossed-roller bearings
  • High dynamic performance

Noncontact Direct-Drive

All of the original ANT series’ direct-drive advantages have been preserved in the ANT-V family. Only noncontact direct-drive technology offers the robust, accurate and high-speed positioning necessary for mass production of precision devices. ANT-V stages utilize advanced direct-drive technology pioneered by Aerotech to achieve the highest level of positioning performance. This direct-drive technology is high-performance, non-cogging, noncontact, high-speed, high-resolution and high-accuracy. This unique drive and bearing combination, packaged in an extremely small-profile and footprint, offers tangible advantages in many 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 ANT-V family has universal mounting and tabletop patterns that allow for easy system integration. Two, three or more axes can be combined easily for flexible system designs and multi-axis configurations.

System Characteristics

Outstanding accuracy, position repeatability and in-position stability require high system resolution. The ANT-V stage’s industry-leading 1 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.
