  • Spectroscopy and imaging system
    Patent number: 11609193
    Abstract: An apparatus and method for characterisation of a sample via spectroscopy and/or imaging. The apparatus comprises a first detector for imaging or spectroscopy, a second detector for imaging or spectroscopy, and a toroidal capacitor type electrostatic energy analyser. The toroidal capacitor type electrostatic energy analyser comprises a first and a second entrance aperture arranged such that charged particles emitted from a sample and passing through the first entrance aperture traverse a first trajectory through the toroidal capacitor type electrostatic energy analyser to be incident at the first detector, and charged particles emitted from a sample and passing through the second entrance aperture traverse a second trajectory through the toroidal capacitor type electrostatic energy analyser to be incident at the second detector.
    Type: Grant
