The wider base makes the ABL1500WB air bearing stage ideally suited for applications with large offset loads, and it is ideal as the lower axis in XY stage systems with large travel. The ABL1500WB incorporates dual linear motors, effectively doubling the force output of a standard ABL1500 stage.
Leading-edge industries, particularly in the semiconductor and high-performance test and measurement fields, demand positioning tolerances beyond the capability of conventional ball-screw and mechanical-bearing positioning systems. The ABL1500WB position stage, with its fully active preload, exceptionally high stiffness, and excellent geometric characteristics was designed specifically to meet those demands.
The ABL1500WB positioning stage incorporates an air-on-air preload on both the vertical and horizontal surfaces. The opposing thin-film pressure maintains the bearing nominal gap tolerance. This design, in addition to the large air-bearing surface that distributes the load over a large surface area, results in a stage with outstanding stiffness that is ideal for heavy or offset loading.
Design Features of the ABL1500WB Air Bearing Positioning Stage Include:
Wide base for large offset loads
450 mm wafer compatible
Powerful dual linear motor drive
Designed for high-performance scanning and inspection
Active air preload on all air-bearing surfaces
Linear encoder feedback provides sub-nanometer resolution
High stiffness for heavy loads and excellent geometric performance
Four models with travels from 200mm to 500mm
