Aerotech direct-drive z-axis nanopositioners achieve 2 nm resolution

The ANT95-L-Z and ANT130-L-Z crossed-roller, z-axis nanopositioning stages offer 25, 35, 50, and 60 mm travels. The company's advanced direct-drive technology enables 2 nm resolution, 75 nm repeatability, and 300 nm accuracy for high-precision positioning, disk-drive fabrication, fiber alignment, optical delay element actuation, sensor testing, and scanning processes. Nearly frictionless counterbalance is adjustable from 0 to 10 kg, depending on stage model.Aerotech
Pittsburgh, PA[email protected] ----- PRESS RELEASE Direct-Drive Z-Axis Nanopositioners Meet the Requirements of Your Most Demanding Positioning Applications • Nanometer performance in a large travel format (25 mm, 35 mm, 50 mm, 60 mm travels) • 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-L-Z crossed-roller, Z-axis, nanopositioning stages are the best-in-class in combining speed, accuracy, resolution, repeatability, reliability and size. They are offered in two models (ANT95-L-Z and ANT130-L-Z) and two accuracy grades. Noncontact Direct-Drive Only noncontact direct-drive technology offers the robust, accurate and high-speed positioning necessary for mass production of precision devices. ANT-L-Z stages utilize advanced direct-drive technology pioneered by Aerotech to achieve the highest level of positioning 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. ANT-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, depending on stage model. Flexible System Design The ANT-L-Z family has universal mounting and tabletop patterns that allow for easy system integration. The entire ANT nanopositioner family of linear, rotary, lift, Z-axis and goniometers can be combined for flexible system designs and multi-axis configurations. System Characteristics Outstanding accuracy, position repeatability and in-position stability require high system resolution. The ANT-L-Z stage’s industry-leading 2 nm minimum incremental step size provides this high level of performance. The excellent in-position stability of less than 2 nm is assisted by high-quality, anti-creep, crossed-roller bearings. These stages offer 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.
