JSM-7800F Field Emission Scanning Electron Microscope

 

Short description:
Scanning Electron Microscope (SEM): a type of electron microscope that permits the observation and characterization of heterogeneous organic and inorganic materials on a nanometre (nm) to micrometre (μm) scale.
 
Main purpose:
The SEM is capable of obtaining 3D-like images of the surfaces of a very wide range of materials. The surface area to be examined or the micro-volume to be analysed is irradiated with a finely focused electron beam, which may be swept in a raster across the surface of the specimento form images or may be static to obtain analysesat one point. Signals produced from the interaction of the electron beam with the sample are in the form of secondary electrons (emitted from the sample), backscattered electrons (from the impinging electron beam) or characteristic X-rays. Signals are obtained from specific emission volumes within the sample and can be used to examine many characteristics of the sample (surface topography, crystallography, chemical composition, etc.).
 
Technical specifications:
The SEM is a JEOL Field Emission Scanning Electron Microscope (JSM-7800F) with maximal resolution of 0.8 nm, acceleration voltage of 0.01 – 30 kV and the magnification range: x25 – x1000000.  
It is equipped with the following detectors:
