Abstract

We revisited the formula related to the overall tilt angle of a specimen using a side-entry double-tilt sample holder in a transmission electron microscope. Initially, we examined existing formulas in the literature for calculating the overall tilt angle. Subsequently, a new formula was derived, proven to better account for the actions of the double-tilt holder, thereby providing improved accuracy in the calculation. This newly derived formula has been implemented in the Landyne software suite. Furthermore, we demonstrated the accuracy of the new formula through examples.

Research Highlights

A new formula has been derived to calculate overall tilt angles for side-entry double-tilt holders in TEM.

重新审视透射电子显微镜双倾斜样品架的倾斜角计算。

我们重新研究了透射电子显微镜中使用侧入式双倾斜样品架的试样整体倾斜角的相关公式。最初，我们研究了文献中现有的整体倾斜角计算公式。随后，我们推导出了一个新公式，该公式被证明能够更好地考虑双倾斜支架的作用，从而提高计算的准确性。这个新推导出的公式已在兰登软件套件中实施。此外，我们还通过实例证明了新公式的准确性。研究亮点：我们推导出了一个新公式，用于计算 TEM 中侧入式双倾角夹具的整体倾角。
