Plot Environment Data
Beam Stability
The section Plot Over Time Parameter is used to configure these plots:
·
The maximum number N of data points in the plots can be defined (N=1 to 100000).
· The time interval between two data points can be selected (between 0 = every measure-
ment to 1000 s; default = every measurement).
· Specify the action performed after the maximum number N of recorded data points is
reached:
o
"Discard First Points" means the 1st data set is discarded and the most recent data
point will be added to the plot. In other words, after reaching the maximum number N of
plotted data points, the plot continues and displays the most recent N data points.
o
"Discard Last Points" means that all data points beyond N will be discarded. In other
words, after reaching the maximum number N of data points, the plot stops.
6.5.6 Translation Stage Control
If a translation stage is detected as is the case when a M2MS measurement extension is con-
nected and powered, the topics "Translation Stage Control" and "M
2
set" appear as the last two
topics of the Beam Settings panel. The description in this section assumes a Thorlabs DDS100
Linear Translation Stage, as it is used in the
M2MS Extension Set .
This panel allows the user to manually control the translation stage. This is useful for a coarse
setup of the M² or
Divergence Measurement .
Actual Position displays the present stage position.
Target Position: Enter a value between 0 and 200 mm, press "Enter" on your keyboard, and
the stage will travel with the set Velocity (see below) to the new position.
