| The specimens were then ground to a fine powder and analyzed individually in an X-ray diffractometer to determine carbonate polymorph mineralogy. |
| One of its tasks will be to calibrate line spacings smaller than currently possible with the imaging diffractometer. |
| The diffraction constant for the diffractometer was calculated using a grating with 0.1 turn spacings. |
| The NRC diffractometer calibrates the average line spacing with an uncertainty much less than the distance between atoms. |
| The small activity in nanometrology continues with the development of a laser interferometer diffractometer using a three-wavelength method. |
| The diffractometer setup makes use of the diffraction of light on periodic lattices. |
