Move Stage During Measure
If the
Move stage during measure
check box is
activated, the stage will move during a measure-
ment (Fig. 133).
This option allows you to move the stage forth and
back during the entire measurement time. This
option is useful during rare event detection when
large, slowly moving objects in extremely small
concentrations have to be registered. Since these
aggregates are diffusing very slowly without such
movement the measurement times would be
prohibitively long. It should be taken into account
that, in this case, the data stream is analyzed with
the coincidence analysis rather than by correlation
analysis.
If the
Move stage during measure
check box is ticked, the following settings are possible in the dialog:
−
Travel distance of the stage in millimeters: Only integer numbers of millimeters are possible. Type
into the
Distance x
and
Distance y
display boxes or use the arrowheads.
−
Speed of the stage: Only the three preset stage speeds 0.48 mm/s, 4.81 mm/s and 24.01 mm/s are
possible. Select 1, 2 or 3 from the
Speed
dialogue box using the pull down menu.
−
Travel direction: The stage can be moved along the x- or y-axis of the stage. In this case the value in
Distance x
or
Distance y
are set to 0, respectively.
Turning points in the stage movement and turbulent medium can cause correlation signals. Watch
out for these artifacts.
Piezo Stage
You have the option to mount a Piezo Stage onto your normal stage. Be sure to select on the control unit
of the Piezo Stage
the closed loop
operation. If closed loop is selected the corresponding LCD will light
up
.
You have to activate the Piezo XY Stage in the
Config
tool in order to make the Piezo stage
available. The Piezo Stage will be used whenever the
Piezo Sage
button is pressed in the
Measure
tool.
The Piezo stage option is only available with the ConfoCor 2.
If you haven't chosen the closed loop operation mode, the Piezo Stage will not work properly in the
LSM 710 and LSM 780 systems-ConfoCor 3 software.
The Piezo Stage allows for 2D translational motion in the x and y direction with a maximum motion of
100 µm in each direction. The resolution is 1 nm. Positioning accuracy using the Piezo Stage is 10 nm and
less.
Movement by the joystick will overrule the Piezo Stage and the normal stage will be addressed.
The position of the Piezo Stage will be centered in respect to the normal stage whenever the
Zero
button
was pressed. Zeroing will display 40.000 in x and y in the
Piezo control unit
and are therefore not the
same numbers displayed in the Software.
