Introduction
Aerotech’s Nanotranslation Crossed-Roller Vertical (ANT-LXV) stages combine speed, accuracy, resolution, repeatability, and reliability within an extremely small footprint. ANT-LXV linear stages offer 2.5 nm resolution, 1 g acceleration, 500 mm/s velocity, 5 kg load capacity, and a standardized universal-base mounting pattern that allows the use of this flexible stage family in a wide range of configurations.

Noncontact Direct-Drive
ANT-LXV stages utilize advanced direct-drive technology pioneered by Aerotech to achieve the highest level of positioning performance. This direct-drive technology is non-cogging, noncontact, high-speed, high-resolution, and high-accuracy, and the use of crossed-roller bearing elements allows high precision, smaller incremental moves to be accomplished reliably and repeatably. This unique drive and bearing combination, packaged in an extremely small-profile footprint, offers tangible advantages in many applications such as fiber alignment, optical delay element actuation, and scanning applications that demand smooth motion.

Flexible System Design
The ANT-LXV family has universal mounting and tabletop patterns that allow for easy system integration. It can be easily combined with other Aerotech stages to create multi-axis configurations.

System Characteristics
Outstanding accuracy, position repeatability, and in-position stability require high system resolution. The ANT-LXV offers industry-leading 2.5 nm or better closed-loop resolution, while advanced, real-time axis calibration systems allow the highest level of system accuracy. High speed, 40 MHz electronic circuitry enables extremely fast positioning, over 500 mm per second, even at 2.5 nanometer resolution. Excellent in-position stability, assisted by high-quality, crossed-roller linear 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.

ANT-LXV stages include an anti-stiction pneumatic counterbalance to hold position against gravity with very little motor current. An integrated precision regulator allows fine adjustment for a range of payloads.
