It can conduct fine observation on ultrathin sections of samples such as tissues and cultured cells, be used to identify and study viruses, analyze the microstructure of nanomaterials, and also assist in the analysis of crystal structures.Technical Principle：The electron gun emits an electron beam. After being accelerated, the electrons penetrate the sample and interact with the sample to generate different signals. These signals are focused by electromagnetic lenses, and finally an image is formed to present the ultrastructure information inside the sample.Performance：The lattice resolution reaches 0.204nm, and the point - to - point resolution is 0.36nm. The acceleration voltage is usually set at 60KV. The magnification is in the range of 4000× to 200,000×. The image resolution can reach 1937×1496, which can clearly show the micro - details of the sample and help researchers deeply analyze the characteristics of the sample.
