Van Nuys, California – OES (Optimal-Engineering Systems Inc.) has added a new, high precision open aperture stage to it's expanding line of precision XY stages. The AU200-100x100 stage is a low-profile stage measuring 80mm (3.150") high with a footprint (including motors) of 348mm x 348mm (13.701" x 13.701"). The linear travel of the X and Y axis is 100mm x 100mm (3.937" x 3.937"), and the resolution of each axis is 20 microns (non-micro-step) or 1 micron (20 micro-steps per step motor driver in use), repeatability is 2 microns, and the positional accuracy is 3 microns.

The stages have preloaded V-groove and crossed roller bearings and ground 4mm per-turn lead screws having just 2 microns of backlash, all contributing to the high precision and stiffness of the AU200-100x100 Stage. Designed for applications such as: Laser drilling, machining, medical, industrial, semiconductor handling, testing, scanning, alignment, assembly, and optical applications, this compact, low profile black anodized aluminum XY stage is easy to integrate into new or existing systems. 

The XY stage's table measures 300mm x 300mm (11.811" x 11.811") and the open aperture measures 188mm x 188mm (7.402" x 7.402"). A recessed mounting and precision pattern of drilled and threaded mounting holes facilitate the alignment of tooling or fixtures. Additionally, solid tooling plates are available for custom and interchangeable applications.

The standard two-phase (1.8o) stepper motors have knobs for manual adjustments of each axis of the stage, however, the knobs can be replaced with incremental encoders for position verification. As an option, servo motors and compatible motion controllers are also available from OES, or the AU200-100x100 Stage can be ordered as a complete plug-and-play motion control system.
