Van Nuys, California – Optimal-Engineering Systems Inc. (OES) has added a new, larger, high load, precision stage to its line of precision XY stages. The AU200-170x170 stage low-profile stage measures 108mm high with a footprint (including the motors) of 458.5mm x 458.5mm. The linear travel of the X and Y axes is 170mm x 170mm, and the resolution of each axis is 20µm (non-micro-step) or 1µm (20 micro-steps per step motor driver in use), repeatability is 2µm, and the positional accuracy is 3µm. The 4mm per-turn lead screws have just 2µm of backlash and the stages have preloaded V-groove and crossed roller bearings contributing to the high precision and stiffness of the AU200-170x170 stage.
Designed for applications such as: alignment, assembly, laser drilling, machining, medical, industrial, semiconductor handling, testing, scanning, 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 and features a precision pattern of drilled and threaded mounting holes to facilitate the addition of tooling or fixtures. Additionally, a table with a large open aperture is available.
The standard two-phase (1.8o) stepper motors have knobs for manual adjustments of each axis of the stage, and the knobs can be replaced with incremental encoders for position verification or closed loop operation. As an option, servo motors and compatible motion controllers are also available from OES, or the AU200-170x170 stage can be ordered as a complete plug-and-play motion control system.
