It can observe the micro surface structures of various samples like metals, ceramics, and biological sections, obtaining information such as surface morphology, particle size and distribution. Equipped with an energy spectrometer, it can conduct micro - area chemical composition analysis.Technical Principle: The electron gun emits an electron beam. Under the action of the acceleration voltage, it is focused by the electron lens and then scans the sample surface. The sample is excited by the electron beam to generate signals such as secondary electrons and backscattered electrons. The instrument collects and amplifies these signals and converts them into images to present the micro characteristics of the sample.Performance: The acceleration voltage ranges from 0.5 - 25 kV, with an operating voltage of 208V, single - phase. It can operate in the conventional high - vacuum or variable - pressure vacuum mode. The magnification can reach a certain multiple (specific value not specified). It is equipped with a secondary electron detector for imaging.
