Alignment
The
Dual Camera Alignment
tool (Fig. 444)
allows to align two cameras of a Duolink to each
other as the rear camera is motorized.
The current positions is displayed in
Alignment
for
X [µm]
.
Y [µm]
,
Z[µm]
as well as
Rot [
o
]
. The
positions can be manually changed by the
respective sliders or via typing numbers in the input
boxes.
Pressing
Store Corrent Pos
will store the current
positions.
Move To Stored Pos
will bring the
positions to the stored ones.
In case auf automatic alignment a
Calibration
Pattern
in the Duolink canbe used if the
Calibration Pattern checkbox is ticked (Fig. 445).
Inthis case no Continuous Scan or laser light iis
needed, as an internal LED lamp will be used for
illumination the pattern.
Press
Adustment XY
,
Adjustment XYRot
or
Adjustment Z
to trigger an automatic alignment
in X and X, X, Y and Rotation or Z, respectively. If
the alignment was successful (Fig. 446), press the

button to save the positions.
You can also use a multi-color bead sample
and laser light tomanually align the cameras.
By Continuous scanning in a 2D view bring
the beads in the 2 channels in aligbnment in
X, Y, Z and Rot.
The alignment is only usable for the beam
path used doing the alignment. You can only
