FEI ESEM Quanta 200 – Environmental Scanning Electron Microscope

ESEM200-4The FEI ESEM Quanta 200 is a versatile scanning electron microscope with three imaging modes. The “high vaccum mode” (HV) is a conventional SEM mode with the need of conventional specimen preparation. In the “low vacuum mode” (LV) electrically non conductive samples can be imaged without the need of a conductive layer (e.g. carbon, gold etc.). Additionally in the “ESEM mode” (ESEM) wet samples can be investigated in their “natural” state.
