Goniometers are used to rotate an object or a sample around a point in space. The center of rotation is located over the center of the table. These gonionmeters can be used either alone or integrated together to accomplish a 2-dimensional tilt motion with common rotation center. A 3-dimensional tilt motion with two different rotation centers is also available.
The mechanism uses precision dovetail slides. A scale is marked on the edge of goiometers to indicate the angle from horizontal.
