IMAGING DEVICE FOR IMAGING AN OBJECT AND FOR IMAGING A STRUCTURAL UNIT IN A PARTICLE BEAM APPARATUS
First Claim
1. An imaging device for imaging an object in a particle beam apparatus and/or for imaging a structural unit of the particle beam apparatus, havingat least one illumination unit having a first switching state and a second switching state for illuminating the object and/or for illuminating the structural unit with illumination light, wherein, in the first switching state, the illumination light comprises only light of a first spectral range and wherein, in the second switching state, the illumination light comprises only light of a second spectral range,at least one control unit for switching the illumination unit into the first switching state or into the second switching state, and havingat least one camera unit for imaging the object and/or for imaging the structural unit with light of the first spectral range in the first switching state of the illumination unit or with light of the second spectral range in the second switching state of the illumination unit.

Abstract
The system described herein relates to an imaging device for imaging an object in a particle beam apparatus and/or for imaging a structural unit of a particle beam apparatus, and to a particle beam apparatus having such an imaging device. The imaging device has an illumination unit having a first switching state and a second switching state for illuminating the object and/or the structural unit with illumination light, where, in the first switching state, the illumination light comprises only light of a first spectral range and where, in the second switching state, the illumination light comprises only light of a second spectral range. The imaging device has a control unit for switching the illumination unit into the first switching state or into the second switching state, and a camera unit for imaging the object and/or the structural unit.
