Abstract
A device comprising a television camera mounted inside the projection chamber of a transmission electron microscope with the imaging surface perpendicular to the optical axis of the microscope. The electron image is converted to a light image by high efficiency YAG transmission scintillator and transferred by a low loss fiber optic plate to a CCD imaging device. The camera is moved by a pneumatic piston between the operating position where it intercepts the electron beam and a position where the electron beam can pass unobstructed to the main microscope viewing screen.
