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.
Claims20
A low-cost, high precision goniometric stage for x-ray diffractography comprising:
- a spherical sector supported on at least one spherical bearing surface;
- a flat upper surface of said spherical sector that is used for mounting a sample or device;
- two intersecting axes of rotation disposed within the sample or the device;
- a connecting member that is attached to said at least one spherical bearing surface;
- movement means to move the connecting member;
- and
- a mechanical linkage between the connecting member and the movement means.
