Claim 0:
1. A method of using a particle beam microscopy system comprising a particle beam source for generating a particle beam, an objective lens for focusing the particle beam on an object and a first deflection device for scanning the particle beam over the object, the particle beam microscopy system being configured to record particle-microscopic images by virtue of using the first deflection device to scan the particle beam over the object, the method comprising:
recording a first particle-microscopic image at a first focus and varying the excitations of the first deflection device within a first range;
changing from the first focus to a second focus;
determining a second range of excitations of the first deflection device on the basis of the first range, the first focus, the second focus and a machine parameter determined in advance; and
recording a second particle-microscopic image at the second focus and varying the excitations of the first deflection device within the second range,
wherein the second range of excitations is determined so that a region of the object represented in the second particle-microscopic image is also represented in the first particle-microscopic image.
