QUANTA FEG 250 – 50 mm STAGE
The stage has the X, Y, Z, and Rotation movements motorised, all
with a manual override and the manual Tilt movement. All movements
are read out on the screen, under software control.
The Z coordinate can be controlled by the external 25 mm Z control
and / or by the 25 mm internal (sample holder) setting. This allows to
load large or differently sized specimens by reducing the internal Z.
