The ANT130-L series stages offer best-in-class performance in speed, accuracy, resolution, repeatability, reliability, travel range, and are offered in two accuracy grades. With its low profile and outstanding performance characteristics, the ANT130-L is the ultimate solution for high-accuracy alignment, inspection, positioning, and measurement stations.

Noncontact Direct-Drive
Unlike many stages that utilize a lead- or ball-screw drive, the ANT130-L employs a center-driven, non-cogging, noncontact linear motor and encoder as the driving element. Since the linear motor is a direct-drive device, there is no backlash, windup, or “stiction” that is normally associated with a lead- or ball-screw drive.

The linear motor drive also offers the advantage of higher speeds and accelerations. The compact yet powerful linear motor drives the ANT130-L to a peak unloaded acceleration of 1 g and a maximum velocity of 350 mm/s. The result is a high-accuracy device with outstanding throughput that significantly outperforms comparable high accuracy screw-driven or other stages in its class.

Outstanding Resolution
For alignment applications, outstanding step-to-step resolution is critical. The ANT130-L meets this demand with an incremental step size of 1 nm when coupled with Aerotech drives and controls. The direct-drive linear motor allows the ANT130-L to make precise, small resolution steps. This is particularly important in alignment applications where step accuracy is critical.

Designed for Long Life
Like all stages in the Aerotech product family, the ANT130-L was designed for outstanding long-term performance. Both the linear motor and linear encoder are noncontact devices, which means they not only exhibit long-life but are totally maintenance free. A moving magnet track design eliminates the need for cable management, further improving long-term reliability.

Precision Alignment
ANT130-L series stages are easily configured as XY assemblies. Options include precision orthogonality alignment to 5 arc seconds and available vertical axis solutions.
