Goniometers
* Rotate about a point in space without obscuring the beam
* One or two axes of rotation about the same point
* Compact square shape
* Three sizes compatible with linear and rotation stages
* Inch and metric mounting holes
* Lockable
Goniometers are used to rotate an object or sample about a point in space. The center of rotation is located over the center of the table and is not obscured by the stage itself. In this way it is possible to have a clear and unimpeded access to the point of rotation. Goniometers are offered with different centers of rotation and can be stacked so that two orthogonal axes rotate about the same coincident point.
These goniometers are square in shape making them compact and convenient to use either alone or in conjunction with other stages. The mechanism uses a leadscrew driven, precision dovetail slide. A Vernier scale is marked on the edge of the goniometers to indicate the angle from horizontal. The drive may be controlled by hand or by means of an Allen key.
