Scanning Electron Microscopy


Scanning Electron Microscopy (SEM)

The JEOL 820 scanning electron microscope at Lehigh Testing Laboratories, Inc. (LTL) in New Castle, Delaware, features a large chamber, which can be accessed in a vent-down mode for oversize components, and a small side-entry port for analysis of smaller samples. LTL also performs energy dispersive spectroscopy (EDS) analysis using an Oxford Instruments light element detector equipped with a 4 pi EDS analysis system.
