SU9000 II
Ultra-high Resolution Scanning Electron Microscope
The CFE Gun technology featured in the SU9000 achieves the highest SEM resolution in the world. (0.4nm at 30kV).
The SU9000II is ideal for high-resolution imaging with a small source size and energy spread. It features unique electron optics, with the sample positioned inside a gap between the upper and lower parts of the objective lens pole piece. With his innovative cold field emission gun technology guarantees the highest possible system resolution (SE resolution 0.4 nm à 30 kV, 0.7 nm à 1kV with deceleration feature) and the highest stability against external disturbances (fields, vibrations, contamination).
SU9000II uses an ultra-stable side-entry stage similar to high-end TEM systems and incorporates optimized vibration damping and a closed cabinet to shield the electron optics from environmental noise.
Furthermore, the clean vacuum concept of the SU9000II offers a vacuum level in the gun and sample chamber that is one order of magnitude than previous generation, minimizing sample contamination artefacts.
New features have been added like to allow automatic adjustments of optical system and the EM Flow Creator software package as an option for automated data acquisition, particularly sequential data collection.
