Abstract
Apparatus include a reflector positioned adjacent to a sample location that is situated to receive a charged particle beam (CPB) along a CPB axis from a CPB focusing assembly so that the reflector is situated to receive light emitted from a sample at the sample location based on a CPB-sample interaction or a photon-sample interaction and to direct the light to a photodetector, and a steering electrode situated adjacent to the reflector so as to direct secondary charged particles emitted from the sample based on the CPB-sample interaction away from the reflector and CPB axis. Methods and systems are also disclosed.
