that the LL-AFM sensor can fit under the bottom of the
zoom tube.
b) Move the micrometers on the video microscope
support to their central position. Move the micrometers
on the TT-AFM stage to their central position. If not
instailed already, install a xyz piezo scanner.
c) Place the TT-AFM stage under the zoom tube such
that the hole in the LL force sensor is directly below the
zoom tube optical objective.
d) Adjust the height of the zoom tube so that the bottom
of the tube is about 115 mm from the top of the AFM
sample holder. Move that stage by hand and adjust the
optical focus.
