THE ANT-4V, available from Lastek , represents a significant breakthrough in vertical alignment of high-precision components.
This unique, patented device incorporates the best high-performance features: high speed (50mm per second), high resolution (2nm), superior in-position stability, and high accuracy (200nm), in one compact package.
Its non-contact direct drive employs high-accuracy direct position feedback. When combined with Aerotech's MXH multiplier, it offers a 2nm 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.
Non-contact, direct-drive technology offers the robust, accurate, and high-speed positioning necessary for mass production of precision devices.
ANT stages utilise 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, non-contact, 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
