Field Emission Scanning Electron Microscope | SEM4000

CIQTEK SEM4000 is an analytical field emission scanning electron microscope equipped with a high-brightness long-life Schottky field emission electron gun.

With the three-stage condenser electron optics column design and the large continuously adjustable beam current, SEM4000 delivers advantages in EDS, EBSD, WDS, and other analytical applications. The system supports low vacuum mode, which can help directly observe poorly conductive or even non-conductive specimens. Standard optical navigation mode, as well as an intuitive user operation interface, makes your analysis work easy.
