Electron Optics Working Mode |
Resolution: High resolution mode
Depth: Sets the column up in a mode that enhances depth of focus
Field: Optimizes the column to provide a large non-distorted field of view
Wide Field: Provides an extra-large non-distorted field of view for extra low magnification imaging
Channeling: Working mode for assessment of crystal orientation data of the specimen, acquiring of electron channeling pattern (ECP).
