    摘要: Disclosed is a device for sustaining different vacuum degrees for an electron column, including an electron emitter, a lens part, and a housing for securing them, to maintain the electron column and a sample under different vacuum degrees. The device comprises a column housing coupling part coupled to the housing to isolate a vacuum; a hollow part defined through the center portion of the device to allow an electron beam emitted from the electron column to pass therethrough; and a vacuum isolation part having a structure of a gasket for vacuum coupling, wherein a difference of no less than 10 torr in a vacuum degree is maintained between both sides of the device by selecting an appropriate diameter of a lens electrode layer which is finally positioned in a path along which the electron beam is emitted or by using the hollow part.
