Abstract

A Transmission Charged-Particle Microscope comprises a source of charged particles which are then directed by an illuminator onto a specimen supported by a specimen holder. Charged particles transmitted through the specimen may undergo energy loss with a distribution of losses providing information about the specimen. A dispersing device disperses the transmitted charged particles into an energy-resolved array of spectral sub-beams distributed along a dispersion direction. The dispersed charged particles are detected by a detector comprising an assembly of sub-detectors arranged along said dispersion direction, whereby different sub-detectors are adjustable to have different detection sensitivities.
