Three dimensional reconstruction of sample rod using transmission electron microscopyIt is the core component for achieving three-dimensional structural analysis of samples. By driving the sample to tilt at multiple angles, two-dimensional projection images at different tilt angles are obtained, and then a three-dimensional structural model is fitted through specialized software processing. It is widely used in the research of nanoscale and even atomic scale structures in materials science, life science and other fields.

Core design and performance points:

Tilt function: This is its core performance. The basic single tilt model can achieve large angle tilt such as ± 90 ° in the alpha direction, while the advanced double tilt model can also synchronously achieve β direction tilt. Some models can achieve a β direction tilt angle of ± 10 °, and the two tilt axes of the double tilt model converge at the center point of the sample, ensuring that the sample does not deviate from the observation range of the electron beam during tilt.

Structural adaptability: High strength titanium alloys and other durable materials are commonly used, and some products adopt double-sided fastening copper mesh design and central symmetrical structure to enhance experimental stability.

Compatible imaging mode: Mainstream products generally support high angle annular dark field imaging in scanning transmission mode, and some models have spatial resolution better than 0.18nm, meeting the three-dimensional reconstruction needs of atomic level fine structures.
