Claim 0:
1. A probe system, comprising:
an enclosure that at least partially defines an enclosure volume configured to at least substantially enclose a substrate that includes one or more devices under test (DUTs);
a testing assembly configured to test the one or more DUTs;
an imaging device configured to generate an optical image of at least a portion of the probe system, wherein the imaging device includes:
(i) an imaging device objective lens that extends at least partially within the enclosure;
(ii) an imaging device body that operatively supports the imaging device objective lens and that is positioned at least partially exterior of the enclosure volume; and
(iii) an objective lens isolator that at least partially electrically isolates the imaging device objective lens from the imaging device body; and
an electrical grounding assembly configured to restrict electromagnetic noise from entering the enclosure volume; wherein the electrical grounding assembly includes an objective lens grounding conductor that electrically connects the imaging device objective lens to an electrical ground; and wherein the objective lens grounding conductor extends at least substantially circumferentially around the imaging device objective lens.
