| Abstract: | The amount of double exposed micrographs needed to completely calibrate a transmission electron microscope was discussed, and a formula for calculating other image _ diffraction pattern rotation angles from those already measured was deduced. The procedure for determining the rotation angles was illustrated using Philiphs CM200 as an example. An instance was given to show how to transfer the crystallographic information from an electron diffraction pattern to a micrograph. |
| Keywords: | Transmission electron microscope Calibration Image _ diffraction rotation angle |
