    摘要: A particle beam apparatus includes a first aperture unit having an adjustable aperture opening. The particle beam apparatus may include a first condenser lens having a first pole shoe and a second pole shoe. Both the first pole shoe and the second pole shoe may be adjustable relative to a second aperture unit independently of each other. The second aperture unit may be designed as a pressure stage aperture separating a first area having a vacuum at a first pressure, and a second area having a vacuum at a second pressure. Additionally, a method for adjusting a beam current in a particle beam apparatus is provided.

    摘要: A method for processing a digital gray value image includes the steps of: generating a binary edge image from the gray value image so that edges present in the gray value image are determined as line areas around the edges; applying a sharpness algorithm in the gray value image within regions which correspond to the line areas; and, carrying out a smoothing process in the gray value image within regions which lie outside of the line areas so that an additional smoothed, sharpened gray value image is generated.

    摘要: The invention relates to a focusing and positioning ancillary device for a particle-optical scanning microscope, a particle-optical scanning microscope including a corresponding positioning aid, and a method for focusing and positioning an object in a particle-optical scanning microscope. The focusing and positioning ancillary device includes an illuminating device, a camera, a display and a control unit. The illuminating device produces a collimated or focused light beam at an angle to the particle-optical beam axis which intersects the particle-optical beam axis at a predetermined position. The camera is sensitive to the wavelength of the light beam and records an image of the object, which is positioned on the object table, at a second angle to the particle-optical beam axis. The control unit produces an image captured by the camera on the display together with a marking which indicates the position of the particle-optical beam axis in the image.
