3.2: Placing Head on Scanner Stage:
A
Once a probe is properly installed in the cantilever
holder, the superluminescent diode (SLD) can be aligned
on the stand next to the base (with kinematic machined
leg divots) IF using the IR card,
-ORover
the sample IF using the CCD camera. To do the
latter, the head must first be placed on the stage.
A detailed description of aligning the SLD is described in
Chapter 4.1A&B, for IR card and CCD camera,
respectively.
B
Lift the head with two hands and place the back two
legs in the kinematically machined divots on the MFP-3D
baseplate (Figure 3.5A).
Move hands so thumbs are under the front of head,
and slowly lower head towards stage using back legs as
pivot point; continually monitoring the tip – sample
separation (Figure 3.5B) with your visual spectroscopy. If
it looks as though the tip will crash, lift/ pivot head back
Figure 3.5: Installing the head onto base plate over
sample: A) use two hands to lift head, set back two legs
onto base plate first; B) gently lower front leg down,
constantly monitoring tip sample distance to avoid tip
crash.
