Parameter
Description
Electron source
Filament:
Schottky field emitter
Automatic emitter run-up:
Safe controlled run-up to the target
emitter conditions
Objective lens
Type:
Gemini electromagnetic/electrostatic objective lens system (80º
conical final lens) with water cooling for best thermal stability and re-
producibility
Focus
Working distance:
Range from 0.1 mm to 50 mm, depending on
operating conditions and stage configuration
Focus compensation:
Automatic compensation to minimize focus
changes over the entire acceleration voltage range
Dynamic focus:
For correction of focus on tilted specimens
Focus wobble:
For assistance in aperture alignment, with adjustable
amplitude and speed
Rotation compensation:
Automatic correction of apparent image
rotation with changes in working distance
Beam shift
For precise adjustment of image position at high magnifications
