Direct-drive Z-axis nanopositioners from Aerotech
Aerotech's ANT-L-Z crossed-roller, Z-axis, nanopositioning stages are described as 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. Key features of the new stages include:
- Nanometer performance in a large travel format (25mm, 35mm, 50mm, 60mm travels)
- High resolution (2nm) , repeatability (75nm) and accuracy (300nm)
- In-position stability of
- Anti-creep crossed-roller bearings
- High dynamic performance
Only noncontact direct-drive technology offers the robust, accurate and high-speed positioning necessary for mass production of precision devices. ANT-L-Z stages utilise advanced direct-drive technology pioneered by Aerotech to achieve the required 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.
ANT-L-Z stages use a nearly frictionless counterbalance mechanism to maintain performance levels while minimising motor heating. The counterbalance is user-adjustable from 0 to 10kg, depending on stage model.
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.
Outstanding accuracy, position repeatability and in-position stability require high system resolution. The ANT-L-Z stage's 2nm minimum incremental step size provides this high level of performance. The excellent in-position stability of less than 2nm 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.
