Abstract

An embodiment of electron microscope system is described that comprises an electron column pole piece and a light guide assembly operatively coupled together. The light guide assembly also includes one or more detectors, and a mirror with a pressure limiting aperture through which an electron beam from an electron source passes. The mirror is also configured to reflect light, as well as to collect back scattered electrons and secondary electrons.
