摘要
The invention relates to the field of physics and relates to an impulse-resolving photo-electron spectrometer, by means of which the physical properties can be determined. The aim of the invention is to provide an impulse-resolving photo-electron spectrometer enabling the device components to have a simple structure with a significantly reduced overall volume. The aim of the invention is achieved by means of an impulse-resolving photo-electron spectrometer comprising components arranged one behind the other in the direction of the optical axis at least in a vacuum and which are each at least one electron emission sample and a focusing system, wherein the focusing system consists of at least one electron lens and at least one detector, wherein the electron lens consists of three cylindrical elements, wherein the first cylindrical element has a potential = 0 and the two subsequently arranged cylindrical elements have a potential of ≠ 0, and wherein the detector is one or more spatially resolved detectors which are arranged in the focal plane of the electron lens.
