Abstract
An integrated optical element and Faraday cup that can measure charged particle beam currents, manipulate light and analyze charged particle beam energy distribution. One boundary of the cup is formed by a lens or other suitable optical element which can be used for manipulating light along the axis of the Faraday cup. The surface of the optical element interior to the cup is coated with a transparent conductor in order to establish the simultaneous functions of taking charged particle beam current measurements, taking energy distribution measurements and manipulating light for such applications as focusing or imaging. A suppressor/blanker/retarder electrode is designed to eliminate spurious current signals that can result from production of secondary electrons by the charged particle beam impinging on the electrode surface.
