Abstract:
1. An apparatus for simultaneous parallel processing of a sample using light energy for optical viewing or surface processing in parallel with a charged particle beam comprising: a charged particle beam generator for transmitting a charged particle beam along a path to a sample; and a first solid rod lens having a light energy delivery apparatus comprising a light energy source for transmitting light energy along a first path to the sample, a prism having an internal reflective surface aligned along the first light energy path to reflect light energy into a second light energy path toward the sample, a portion of the prism and reflective surface being removed for passage of the charged particle beam, a lens adapted to be aligned along the second light energy path and having a portion removed therefrom for passage of the charged particle beam, the removed portions of the prism and lens adapted to be aligned along the charged particle beam path to permit parallel delivery of the charged particle beam through the removed portions of the prism and the lens and of the second light energy path through the lens and onto substantially the same portion of the sample; a second solid rod lens; and an optical path for transmitting light energy reflected from the sample through the lens and reflected off the prism into the second solid rod lens towards a light energy detector.
