2. Verify the laser beam is visible on the surface below. If it is not, turn the rear-right laser
control knob counter-clockwise until the laser spot appears on the surface below.
3. Turn the rear-right laser control knob clockwise to move the laser in the X positive direction
until the laser spot disappears from the surface below. Turn the right-rear laser control knob
counter-clockwise until the laser spot just reappears. The laser is now positioned at the edge
of the substrate (see Point 1 in

4. Turn the front-left laser control knob clockwise or counter-clockwise to move the laser in the
Y direction (parallel to the substrate edge and perpendicular to the cantilever) until the beam
crosses the cantilever and a shadow appears over the laser spot on the surface below. The
laser is now positioned over the cantilever (see Point 2 in
5. Verify that the laser is deflecting off the cantilever by moving the laser on, over, and off the
cantilever by turning the front-left laser control knob less than 1/8 of a turn.
6. Turn the rear-right laser control knob counter-clockwise to move the laser in the X negative
direction on the cantilever until the laser crosses the tip-end of the cantilever and falls on the
surface below.
7. Move the laser onto the tip-end of the cantilever by reversing the direction of the rear-right
laser control knob clockwise until the spot disappears from the surface below (see Point 3 in
8. Verify that a laser spot appears in the Dimension head filter screen. If there is not laser spot,
adjust the photodetector mirror using the photodetector adjustment knobs located on the left
side of the SPM head (see
CAUTION:
Use extreme caution when removing the SPM head. Hold the head
firmly and do not stress the wire between the SPM head and the
Dimension base. Dropping the head will likely result in damage
and Veeco factory repair.
