Aerotech's ANT-L-Z crossed-roller, Z-axis, nanopositioning stages combine speed, accuracy, resolution, repeatability, reliability and size. They are offered in two models (ANT95-L-Z and ANT130-L-Z) and two accuracy grades. The stages utilize direct-drive technology 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.
The 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. The product 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. The stage's 2 nm minimum incremental step size provides this high level of performance. The 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.
