It is especially suitable for observing the surface microstructure of large objects. Advantages of electron microscope: 1. Powerful view output function: (can directly drive CRT/LCD monitor, computer, TV) 2. High-definition digital imaging combination: (improve detection efficiency, detection quality and accuracy) 3. Observation in horizontal movement state, smooth view without smear: (save work time) 4.Color-changeable crosshair cursor: easy to distinguish the color difference effect of the measured object, an.
