An electron spectrometer is an analytical instrument used to measure the energies and distributions of electrons ejected from a material when it is bombarded with a source of energy, such as X-rays or ultraviolet light. It is widely used in fields such as material science, surface science, and solid-state physics to study the electronic structure and properties of materials.
