Manual Goniometer Stages are Also Available

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. 

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. 

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.

T-Cube DC Motor Controller for Z8 Actuator

 

The TDC001 DC Motor Controller T-Cube is a perfect match for the the Z812 actuators sold above with the GNL series goniometers.

Be sure to purchase a power supply with the TDC001. The TPS001 can power one TDC001 while the TDC008 can power up to eight TDC001 T-Cubes. When using multiple T-Cubes and their USB interface, consider the TCH002 Hub. The hub not only powers up to six T-Cubes but also allows all six T-Cubes to be controlled through the hub's single USB input. Click here for more information on T-Cube power supply options.
