Advantages
1.Schottky Schottky field emission electron gun has high brightness, good monochromaticity, small electron beam spot and long life.
2.Non-conductive samples with low acceleration voltage can be directly observed without spraying gold
3.With high beam stability and low dispersion, it is suitable for long-term accurate analysis, such as CL, EDS, EBSD.
4.Non-conductive samples with low acceleration voltage can be observed directly without gold spraying.
5.Easy to operation.
