Aerotech introduces its latest air-bearing stage series, the ABL2000. ABL2000 air-bearing stages are available in travel lengths up to 1.2 meters and speeds from 0.1 mm/second to 3 meters/second. A wide range of feedback devices is offered, from cost-effective linear encoders to ultra-high resolution laser interferometers. An intelligent and robust cable management system (CMS) makes system integration easy and results in millions of cycles of maintenance-free operation. The standard CMS is designed to incorporate customer cabling, easing integration.

Resolution and accuracy with a non-contact linear encoder are 20 nm and ± 1 micron, respectively. A laser interferometer transducer option provides resolution to 0.3 nm and submicron accuracy. Exceptional positioning characteristics coupled with high speed and acceleration capabilities make these stages the ideal solution for high accuracy and high throughput applications.

The ABL2000 series stages feature exceptional pitch, roll and yaw characteristics (± 1 arc-second/100 mm) due to Aerotech’s proprietary manufacturing techniques that produce stages with unsurpassed geometrical accuracies. Design features of these stages include a small cross section for a narrow profile and large air-bearing surfaces for excellent stiffness and load carrying capability.

Aerotech-manufactured brushless linear servomotors drive ABL2000 air-bearing stages. Optimized by Aerotech engineers for high-performance positioning applications, the brushless linear motors feature an ironless design, eliminating attractive forces, and very low ripple, resulting in extremely smooth stage motion.

To achieve positioning systems with unequaled velocity stability and accuracy, Aerotech also manufactures complementary lines of drives and motion controllers. Aerotech drives and controllers incorporate unique circuit designs and control algorithms necessary to achieve high-performance motion control.

Because all of the core elements of the motion platform — mechanics, motors, drives and controls — are manufactured by Aerotech, systems are fully optimized and tested as a turnkey system prior to leaving Aerotech's state-of-the-art facility. OEMs and end users alike can benefit from a high-performance system at cost-effective prices.

ABL2000 stages are available in standard and custom versions. Applications include high-resolution imaging, fiber-optic micromachining, and general metrology. Pricing begins at under $10,000 for single quantities and delivery is six to eight weeks.
