…imaging advantages of low-voltage operation with improved penetration depth and analytical capability compared to earlier systems. In addition to TEM and STEM imaging modes, it integrates energy-dispersive X-ray spectroscopy (EDS), enabling elemental analysis of thin specimens. This extended voltage range…
