Chapter 5 - Usability, comfort, and options

The graphical user interface for controlling the SEM must be intuitive and simple, while allowing access to advanced parameters (eg, apertures, bias, beam current). Providing captured images directly with measurements and comments can be helpful, as well as the simultaneous display of BE and SE images. 

Intuitive operation is a must for contemporary SEM-EDX devices

Comfort and options

Especially in the field of tabletop SEM and compact devices, the offered comfort features and options of the individual manufacturers differ in some cases very clearly. You should note the following checklist:

1. Digital Macro camera to take a digital photo supports easy navigation on the specimen

2. Panorama function for high-resolution imaging of large sample areas by automatic mosaic grid

3. motorization The axes (XYZRT), in particular a tilting of the sample may be interesting if your sample shows topographic structures

By tilting the sample, the spatial topography becomes clearly visible

4. low vacuumMode to microscopy non-conductive samples directly without sputtering

5. Simple sputtering apparatuses to the conductive coating to microscopy insulating preparations in high resolution

6. STEM detectorto investigate organic thin sections in the transmission image

7. Special rehearsal stage with Peltier coolingto microscopy vacuum-stable samples (eg biological preparations, polymer foams)
