CALCULATION OF TILT ANGLES FOR OBTAINING STEREO TRANSMISSION ELECTRON MICROGRAPHS FROM CRYSTALLINE SPECIMENS
The realisation of stereo pairs from crystalline specimens in the transmission electron microscope requires that the image contrast is the same before and after the stereo tilt. Formulas are derived that enable the calculation of the angles towards which the sample must be tilted in order to obtain a desired stereo tilt angle. Apart from the starting angles, this technique requires the stereo tilt angle and the diffraction spot position as input parameters. Calculation of the desired tilt angles allows the sample to be tilted in the image mode which avoids losing the sample area of interest. This new technique moreover reduces the experimental time to less than five minutes.
