Abstract:
1. Transmission electron microscope in which a sample can be positioned in a sample plane, wherein the microscope comprises: an objective lens positioned downstream of the sample plane in the beam path of the microscope; a first projection lens system having plural lenses positioned downstream of the objective lens in the beam path; a second projection lens system having plural lenses positioned downstream of the first projection lens system in the beam path; and an analyzing system including at least one lens positioned downstream of the second projection lens system in the beam path; wherein the objective lens, the first and second projection lens systems and the analyzing system are configured a) the intermediate image plane is imaged into an entrance image plane of the analyzing system and the intermediate diffraction plane is imaged into an entrance pupil plane of the analyzing system by the second projection lens system, or b) the intermediate image plane is imaged into the entrance pupil plane of the analyzing system and the intermediate diffraction plane is imaged into the entrance image plane of the analyzing system by the second projection lens system.
