title: Image forming optics with a common aperture for fast switching between TEM magnified image and selected area diffraction.
abstract: Image-forming optics that can switch between a magnified image and its diffraction pattern without any movement of aperture is proposed. Both the images are alternately taken and are simultaneously shown in a monitor. This type of optics is applied to the design of an ultrahigh-voltage electron microscope (H-3000) and is tested at 100 kV TEM.
