Abstract

A magazine plate camera which provides for 8 to 16 separate exposures on 314×4 plates without disturbing the vacuum has been built for use with a high magnification electron microscope. Visual focusing of the image formed by the electron beam on a fluorescent screen is possible before each exposure. The camera is compact and the mechanical operation is smooth and positive. It is presumably generally adapted to photography in vacuum apparatus.
