ELECTRONIC MICROSCOPE Russian patent published in 2007 - IPC H01J37/26 

FIELD: microbiology; infection disease prophylaxis.

SUBSTANCE: proposed electronic microscope has tube one of whose ends is connected to vacuum pump and other one is disposed within microscope case past magnetic condenser and tightly closed with hemispherical plug. The latter has slits, 10 to 0.01 μm wide. Indoor air enters case and is exhausted through plug slits by means of vacuum pump. Microbes and viruses are stopped by plug slits. Electron flux magnified by anode and straightened by magnetic condenser leaves cathode and passes by hemispherical plug which holds up microorganisms. Magnified image of microorganisms is projected onto photographic plate. Microbes and viruses detrimental to human health can be determined by image on photographic plate.

EFFECT: improved design.
