It can be used to observe the microstructure of cells and analyze the internal characteristics of materials.Technical Principle: An electron beam is emitted to penetrate the sample. The electrons interact with the sample, and the electrons passing through the sample are focused and imaged by electromagnetic lenses to obtain the internal structure information of the sample. Equipped with an energy spectrometer, it can conduct composition analysis based on the characteristic X - rays generated by the interaction between electrons and the sample.Performance: The acceleration voltage range is 40 - 100kV. The point resolution is 0.45nm, which can clearly show fine structures. The camera lengths are optional as 100mm, 200mm, and 400mm. The magnification range is 25 - 200000 times. It has an advanced variable pressure device and can work in an ultra - low vacuum mode to achieve fast or high - resolution imaging. It is equipped with an automatic stage control and an adjustable specimen holder, which is convenient for sample positioning and movement.
