Abstract
Apparatus, methods and systems are provided to inhibit a sightline from a charged particle source to an analyzer and for changing a baseline offset of an output spectrum of an analyzer. A supply of charged particles is directed through a hollow body of a deflector lens that is positioned relative to a charged particle source and an analyzer. A flow path along a preferred flow path through a deflector lens permits passage of the ions from the source to the detector while inhibiting a sightline from the detector to the source in a direction parallel to the central longitudinal axis of the deflector lens.
