It can also be used for the research of magnetic samples, pure virus suspensions, macromolecules and nanomaterials.Technical Principle：The electron gun emits an electron beam. After the electron beam penetrates the sample, it is focused and imaged by multiple - stage electromagnetic lenses. The path of the electron beam is controlled by an accurate electron - optical system to obtain high - resolution images.Performance：The lattice resolution reaches 0.204nm, and the point - to - point resolution is 0.36nm. The acceleration voltage is 60KV, and the magnification is between 4000× and 200,000×. The image resolution can reach 1937×1496, which can clearly show the microstructure of the sample.
