Design Of Detector Optics For A Low Energy SEM
Our paper describes the design of detector optics for a low-energy SEM (LESEM) with a cathode lens. The cathode lens not only determines the optical properties of LESEM but it also accelerates the signal electrons into the column, where the signal el...
