It can be used for observing the ultrastructure within tissue cells of animals, plants, microorganisms, etc., such as mitochondria, as well as for observing the ultrastructure of nanomaterials and soft materials.Technical Principle：An electron gun emits an electron beam, and after the electron beam penetrates the sample, it is focused and imaged by multiple - stage electromagnetic lenses. Its dual - mode objective lens supports various observation modes such as low - magnification, wide - field high - contrast, and high - resolution in one microscope. Advanced motion control algorithms and sensors are used to ensure accurate imaging.Performance：The resolution reaches 0.2nm. The acceleration voltage can be adjusted in the range of 20 - 120KV with a step of 100V. In terms of magnification, the high - contrast mode is 200 - 200000 times, the high - resolution mode is 4000 - 600000 times, and the low - magnification mode is 50 - 1000 times. It has functions such as automated image stitching and 3D tomography, and can be operated under normal room light.
