Goniometer n. An instrument for measuring angles, especially the angles of crystals, or the inclination of planes.

Contact goniometer, or Hand goniometer, a goniometer having two movable arms (ab, cd), between which (at ab) the faces of the crystals are placed. These arms turn about a fixed point, which is the center of the graduated circle or semicircle upon which the angle is read off.
