Abstract
To form a phase contrast or amplitude contrast image in a transmission electron microscope a beam tilting device (26) is arranged in an objective lens pole (8) before the object stage (11), and is used to switch the electron beam periodically between two tilt positions. The image formed using each tilt position is respectively added or subtracted in a display device (31) controlled by a tilt and sync generator 30 to provide a resultant contrast picture. <IMAGE>
