The ANT-4V represents a significant breakthrough in vertical alignment of high-precision components. This unique, patented device incorporates the best high-performance features: high speed (50 mm per second), high resolution (2 nm), superior in-position stability, and high accuracy (200 nm), in one compact package. Its superior noncontact direct drive employs high-accuracy direct position feedback. When combined with Aerotech's MXH multiplier, it offers an industry-leading 2 nm resolution in addition to high speed and accuracy.

All the critical elements of the ANT-4V were selected to operate in a 24/7 environment and, unlike screw- or piezo-based vertical stages, the ANT-4V requires no maintenance and will assure years of trouble-free operation.

Noncontact Direct Drive
Only noncontact direct-drive technology offers the robust, accurate, and high-speed positioning necessary for mass production of precision devices. ANT stages utilize advanced direct-drive technology pioneered by Aerotech (patent pending) to achieve the highest level of positioning performance. This direct-drive technology is high-performance, non-cogging, noncontact, high-speed, high-resolution, and high-accuracy. This unique drive technology offers a significant (several times higher) throughput advantage over conventional screw and piezo-drive-based systems.
