The dovetail groove type goniometer stage is for rotating an object at a certain angle or moving it around one point in space. The center of rotation is in the center of the table and is not hidden by the stage. This allows the rotation point to be seen clearly. The goniometer has four sizes of square areas, 40, 60, 80, 100mm. Also, it has a different rotation center height and is made for two perpendicular axes to rotate around a meeting point.
The rotation center height is measured from the top of the table. The goniometer can be used on its own or combined with other stages. This moves by a worm gear and worm screw, and there are methods that use fine dovetail sliders and linear ball guides. All models have locks.
