Goniometer stage GN series

for high-precision angular alignment

Features Pure Rotational Motion About a Virtual Point 1° Graduation Marks on Side Backlash-Free Spring-Loaded Design Fully Lockable Small Platform Goniometer Stage: 1" x 1" Large Platform Goniometer Stage: 1.5" x 1.5" 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 goniometers use a backlash-free leadscrew in the smaller GN series and a precision micrometer for enhanced angular positioning of the top plate in the larger GNL series. 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 GN series, the GN05 mounts atop the GN1. In the GNL series, the GNL10 mounts atop the GNL18. These two axis stage setups can be purchased as a single package (GN2 or GNL20 respectively).
