SED

Secondary Electron Detector
for greater topography imaging

Thanks to a highly effective secondary electron collection, SED guarantees a sufficient brightness even for low particle emissions. Based on the Everhart-Thornley detection principle, Orsay Physics SED achieves high dynamic imaging. It includes a scintillator, a light pipe and a photomultiplier to intensify effectiveness of gathered secondary electrons.
It is customized to perfectly fit into any vacuum chambers and to ensure the best image quality.
