FEI ESEM Quanta 600 – Environmental Scanning Electron Microscope
The FEI ESEM Quanta 600 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. The thermally assisted field emission gun (FEG) delivers high brightness of the electron beam and high imaging resolution. Additionally the microcroscope can be equipped with a tensile stage, a Peltier cooled specimen stage, a heating stage and an in situ ultramicrotome.
Key Features
- Seamless "point and click" transition between imaging modes
- Superior low vacuum, low kV imaging simultaneous secondary electron (SE) and backscattered electron (BSE) imaging in LV mode
- Allows for in situ dynamic experiments
- True surface (SE) imaging in all vacuum modes and voltages
- Easy-to-use, four quadrant/single quadrant user interface
