Original Press Release:

High Precision, XAB Triple-Axis (2 Goniometers and X-Axis) Stage Available from OES!

Van Nuys, CA – Optimal Engineering Systems, Inc. (OES) offers a very low cost solution for the precise measurement of compound angles or the rotation of an object to precise angular positions. 

The XAB-050-XX-01 integrates a two-axis Alpha-Beta goniometer on top of a single-axis linear actuator. The Beta-axis has a travel range of +/- 15 degrees with a rotation height of 50 +/- 0.2 mm. The size of the table is 65 by 65 mm (2.559 by 2.559 inches). The gear ratio is 1 degree (stage): 252 degree (motor). The travel mechanism is precision crossed-roller guide.
The lower goniometer (A-axis) has +/- 10 degrees of rotation driven by a worm gear with a drive ratio of 352 degrees of motor rotation to 1 degree of stage rotation.

The Alpha and Beta axes have a calibrated indicator to display the angle of rotation which is ideal for: Crystallography, metrology, light measurement, measurement of surgical cutting blades, microscopy, laser positioning, and inspection applications.

The threaded mounting holes in the Beta-axis and mounting holes in the X axis assure easy integration into new and existing applications. 

The low profile X axis stage has a travel length of 50 mm. The lead screw pitch is 1 mm per turn that yields high resolution and accuracy. Additionally, all axes have end-of-travel limit switches.

The XAB-050-XX-01 (pictured) features Two Phase Stepper Motors with knobs for manual adjustments which can be replaced with optical encoders for position verification. The XAB-050-XX-02 is driven by Three Phase Brushless Servo Motors with quadrature Incremental Optical Encoders for closed loop operation that offer the highest resolution, repeatability, and travel speeds.

Both stages can be ordered Plug-and-Play with a fully compatible controller from OES.
