Aerotech ANT-L-Z stages combine speed, accurancy, resolution and reliability.

]Aerotech introduced a line of ANT-L-Z crossed-roller, Z-axis, nanopositioning stages, offered in two models (ANT95-L-Z and ANT130-L-Z) and two accuracy grades. Utilizing non-contact direct-drive technology, the ANT-L-Z stages provide nanometer performance in a large travel format (25 mm, 35 mm, 50 mm, 60 mm travels). The line also features high resolution (2 nm), repeatability (75 nm) and accuracy (300 nm) with in-position stability of less than 2 nm, assisted by anti-creep, crossed-roller bearings. TheANT-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.
