OES (Optimal-Engineering Systems, Inc.) has added an open aperture stage to it’s expanding line of precision XY stages. The AU200-100×100 stage is a stage measuring 80 mm (3.150 in.) high with a footprint (including the motors) of 348 mm x 348 mm (13.701 in. x 13.701 in.). The linear travel of the X and Y axes is 100mm x 100mm (3.937 in. x 3.937 in.), 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 4 mm per-turn lead screws having 2 microns of backlash. 
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 300 mm x 300 mm (11.811 in x 11.811 in.) and the open aperture measures 188 mm x 188 mm (7.402 in. x 7.402 in.). 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 AU200-100×100 Stage can be ordered as a complete plug-and-play motion control system.
