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 +/- 15o of rotation at speeds to 10o/sec, features a 400:1 worm gear ratio and a resolution of 0.0005o 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 (1.8o) 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.
