  • Patent number: 11810751
    Abstract: The disclosure relates to a method of imaging a specimen using a transmission charged particle microscope, said method comprising providing a specimen, and providing a charged particle beam and directing said charged particle beam onto said specimen for generating a flux of charged particles transmitted through the specimen. The method comprises the step of generating and recording a first energy filtered flux of charged particles transmitted through the specimen, wherein said first energy filtered flux of charged particles substantially consists of non-scattered and elastically scattered charged particles. The method as disclosed herein comprises the further step of generating and recording a second energy filtered flux of charged particles transmitted through the specimen, wherein said second energy filtered flux of charged particles substantially consists of inelastically scattered charged particles.
    Type: Grant
