28 - SEM of Li2O.2B2O3

28 - SEM of Li2O.2B2O3

Description: Electron Microscope: ZEISS SUPRA 55–VP Emitter: Thermal field emission type Date: 15th May 2007 Location: Microscopy lab, Physics, Campus Magnification: 800x Electron Potential: 20 kV Detection: Secondary Electron Comments: Scanning electron microscopes are much like cameras; you have to control the focus, brightness, contrast, zoom level. They are also very unlike optical equipment; focus in x and y is controlled separately, you can choose to detect back–scattered electrons or secondary electrons (and more), you also get to pick how much energy the electrons have as they smash into your sample, and it's all done in a vacuum. Post–processing: False–coloured
