  • Detection device and particle beam device having a detection device
    Patent number: 8513604
    Abstract: A detection device and a particle beam device having a detection device ensure a good efficiency in detecting interaction particles and electromagnetic radiation. The detection device has a detector for detecting electromagnetic radiation and/or interaction particles and a filter element through which the electromagnetic radiation is transmitted. The filter element prevents the interaction particles from striking the detector such that the filter element is situated to move between a first position and a second position, the filter element in the first position being situated in relation to the detector in such a way that the filter element prevents the interaction particles from striking the detector. The filter element in the second position is situated in relation to the detector in such a way that the filter element allows the interaction particles to strike the detector. As an alternative, the filter element may be an object holder.
