Title: Electron microscope
Inventor: ARAI YOSHIHIRO
IPC: H01J37/26
Filed: 1991-11-21
Abstract: PURPOSE:To prevent a blur of an image, and also prevent a drift of a sample by operating a shutter deflecting coil arranged closer to. the fluorescent screen side than a sample and a deflecting coil arranged on the electron gun side relationally to each other. CONSTITUTION:When a photograph is taken, an electric current is supplied to a shutter deflecting coil 11, and a deflecting magnetic field C is formed. Electron beams are removed from the optical axis O. A fluorescent screen 13 is put in an upward condition. When a time (ts) passed after a shutter is turned on, it is turned off again, so that the deflecting magnetic field by means of the coil 11 is extinguished. Immediately before it, a deflecting coil 10 is put in on condition D, and a deflecting current is supplied for a time (tB). The electron beams are removed from the optical axis O due to this deflecting magnetic field, and are returned to the optical axis O simultaneously when the deflecting magnetic field is extinguished, and a photographic film 14 starts to be exposed. Since magnetic materials are few in the vicinity of the deflecting coil 10, a change in the deflecting magnetic field becomes sharper than that of the deflecting coil 11. A blur cause time range (tA) can be treated within an exposure time until the next on condition of the coil 10. Since the operation time of the coil 10 is about 0.1 second, the drift of a sample 12 can be neglected.
