Abstract
Disclosed is a charged particle beam system, which includes: a particle source, a column and a specimen chamber with a first movable vacuum window. The particle source is configured to generate a charged particle beam which impinges the specimen to be detected placed in a specimen chamber. The column includes a deflection device for deflecting the charged particle beam and a focusing device for focusing the charged particle beam. The charged particle beam system is compatible with multiple external optical systems to achieve simultaneous detection or fast-switching detection of the specimen. An opto-electro simultaneous detection system and the method are also disclosed.
