Linear Stage
The linear positioner is a fully preloaded, noncontact design. Inherently frictionless, air bearings have proven to be the standard in precision applications, and Aerotech has now produced a miniature version that is well-suited for the photonics industry. Driven by a noncontact linear brushless servomotor, this stage proves the ultimate solution whether the application requires small, accurate steps or constant smooth velocity. Years of research have resulted in a robust and perturbation-free cable management system.
Feedback and Control System
Directly coupled, noncontact linear encoder position feedback is available with different options. A wide selection of state-of-the-art controllers is available, featuring the Automation 3200 software controller with digital drives.
Options
Convenient rack or panel-mount amplifiers are included with all systems. Aerotech’s expert technical staff is experienced in custom system designs and will work with you to generate a system to meet the unique needs of your application.
Clean Room Compatibility
The air-bearing design is inherently clean room compatible. A high quality cable management system, together with low particulate generation materials, provides compliance to Class 1 with proper integration.

- Maximum speed based on stage capability; maximum application velocity may be limited by system data rate and system resolution.
- Values with Aerotech controls and calibration.
- Dependent on flatness of stage mounting surface.
- To protect air bearing against under-pressure, an in-line pressure switch is required and tied to the controller E-stop input.
- Air supply must be clean, dry to 0° F dew point, and filtered to 0.25 µm or better; recommend nitrogen at 99.99% purity.
- Maximum expected air consumption for a three-axis system.
