An electron microscope comprising a microscope chamber having a passageway extending therethrough and a film mechanism for driving an electron stimulated means, or film plate, into the microscope chamber. The film mechanism includes a tray disposed within the microscope chamber and communicating with the passageway, a closure member positioned across the passageway for preventing the passage of X-rays through the passageway, a storage chamber disposed externally of the microscope for storing a film plate, and transport means for driving a film plate from the storage chamber to the tray so that the film plate is moved to a position to intercept a beam of electrons passing through an object to be viewed.
