The XAB-050-XX-01 from Optimal Engineering Systems, Inc. (OES) is a low-cost solution for the precise measurement of compound angles or the rotation of an object to precise angular positions. It integrates a two-axis Alpha-Beta goniometer on top of a single-axis linear actuator. The Beta-axis has a travel range of +/- 15° with a rotation height of 50 +/- 0.2 mm. The size of the table is 65 x 65 mm (2.559 x 2.559 in.). The gear ratio is 1° (stage): 252° (motor) and the travel mechanism is precision crossed-roller guide.
The lower goniometer (A-axis) has +/- 10° of rotation driven by a worm gear with a drive ratio of 352° of motor rotation to 1° 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 and the lead screw pitch is 1 mm per turn that yields high resolution and accuracy. All axes also have end-of-travel limit switches.
The XAB-050-XX-01 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.
