    Abstract: PROBLEM TO BE SOLVED: To provide an electron beam apparatus with high electron beam intensity in order to achieve a high throughput in a desired signal-to-noise ratio.SOLUTION: An electron beam apparatus 100 comprises: a beam emitter 102 to emit a primary electron beam 101; an objective electron lens 125 to focus the primary electron beam 101 on a sample 130 and to define an optical axis 126; a beam separator 115 having a primary dispersion in order to separate a signal electron beam 135 from the primary electron beam 101; and dispersion compensation elements (104, 204). The dispersion compensation element 104 having a secondary dispersion is suitable for adjusting the secondary dispersion independently from the tilt angle of the primary beam 101 located downstream of the dispersion compensation element 104 so that the secondary dispersion fully compensates the primary dispersion, and is located upstream of the beam separator 115 along the primary electron beam 101.
