Optimal Engineering Systems, Inc. (OES) offers a very low cost solution for the precise measurement of angles or the rotation of an object to a precise angular position.  This 160 mm x 160 mm stage with +/- 15^o of rotation at speeds to 10^o/sec, features a 400:1 worm gear ratio and a resolution of 0.0005^o with a 10 micro-step per step stepper motor driver; the stage is also available with a servo motor and optical encoder.  This low profile Goniometer stage is just 100 mm high and the height of the rotation center at 139 mm is ideal for: Crystallography, light measurement, measurement of surgical cutting blades, microscopy, laser positioning, and inspection applications.

The precision worm gear and crossed roller guides provide the high precision, (Repeatability of +/- 3 arcsec, Accuracy of  +/- 8 arcsec, and Backlash of +/- 3 arcsec) needed for critical measurement and inspection operations.  This compact, black anodized Motorized Goniometer Stage measures just 340.5 mm long (including the standard (1.8^o) stepper motor and 160 mm wide and can handle loads to 30 Kg.  Mounting holes on the stage and in the base assure easy integration into an application.  A calibrated indicator displays the angle of rotation, a hand knob is provided for manual adjustment, and the stage can be ordered with a fully compatible controller from OES.
