Any help would be welcome especially in future as the voltages climb. However, most vacuum ports are not lead glass and a specially machined and gasketed port would have to be supplied for adapting the lead glass. Finally the E-beam absorption for lead glass might result in unacceptable amounts of heating which is a no-no for glass in a vacuum system.
I'll check into the leaded glass more, but the mirror bit (Jim Lux) sounds infinitely more doable for the camera. A major lens change would be in order and the field of view greatly diminished with the mirror scheme, however.
