A goniometer or goniometric stage is a device used to rotate an object precisely, within a small angular range, about a fixed point in space. Goniometers are similar to linear stages, but, rather than providing linear movement, the stage partially rotates about a fixed point above the mounting surface of the stage. In our two product lines, the distance from the point of rotation to the mounting surface was designed so that two different goniometer models may be stacked in an X-Y configuration and both stages will rotate about the same point. Our motorized goniometers use our Z812B DC Servo Actuator for enhanced, automated, angular positioning of the top plate.

Our goniometers offer unobstructed, pure rotational motion about their point of rotation over the angle of rotation (see image to the right). The compact, stackable design allows one model to be fastened to the top plate of another aligning their points of rotation. In the GNL series, the GNL10 mounts atop the GNL18. These two axis stage setups can be purchased as a single package (GNL20) at a cost savings.

The precision dovetail design, accompanied by a backlash-free lead screw and a vernier scale, provides accurate and repeatable positioning. A side mounted setscrew can be used to lock the platform in position.

The GNL series goniometers provide a generous array of taps [4-40 (M2.5) and 6-32 (M4)] for mounting. See below or the Specs tab for mounting hole position.

The TDC001 DC Servo Controller is the ideal driver for the Z8 series actuators. Please note that older TDC001 units will require a firmware upgrade to V1.0.10 or later, before they can be used with the Z8 series motors. An upgrade is included with the latest APTServer software, which can be downloaded here.

The Z812 DC servo motors shipped with these stages are provided with 1.6' (0.5 m) of cable. A 8' (2.5 m) extension cable, PAA632, is also available.
