A cylindrical member that is formed with conductors stacked as an inner layer and an outer layer, and an insulator stacked as an intermediate layer is provided inside a lens tube into which the secondary electron optical system is incorporated. An electron orbital path is formed inside the cylindrical member, and the members constituting the secondary electron optical system are arranged outside the cylindrical member.

  • Patent number: 9966227
    Abstract: A technique capable of improving the ability to observe a specimen using an electron beam in an energy region which has not been conventionally given attention is provided. This specimen observation method comprises: irradiating the specimen with an electron beam; detecting electrons to be observed which have been generated and have obtained information on the specimen by the electron beam irradiation; and generating an image of the specimen from the detected electrons to be observed. The electron beam irradiation comprises irradiating the specimen with the electron beam with a landing energy set in a transition region between a secondary emission electron region in which secondary emission electrons are detected and a mirror electron region in which mirror electrons are detected, thereby causing the secondary emission electrons and the mirror electrons to be mixed as the electrons to be observed.
