ABSTRACT:
A low-cost, high precision goniometric stage, for use in x-ray diffractography or in optical systems, with a spherical sector supported on at least one bearing, a top surface of the spherical sector that is used for mounting an object, a center of rotation located within the object, a rod or other member that is disposed below the spherical bearing surface, preferably orthogonal to the rotational axes, stepper motors or other actuators to move the device and a mechanical linkage between the rod and the motors.
