full range of the device, but may be less accurate within the calibration
range.
Both single and multipoint calibrations will save the new calibration co-
efficients on the device. They also save all calibration points (measured
and known wavelengths) to a
.csv
file.
To avoid reprogramming the device with new calibration data, hit the
Cancel
button.

Calibrating with
MOGL
abs FZW wavemeter
If you have access to a
MOGL
abs
FZW
Fizeau wavemeter, you can auto-
matically load the known wavelength from the
FZW
measurements in real
time, making calibration very fast. The
FZW
must be connected by
USB
to
the same computer that is running
mogwave
, or accessible via ethernet.
Click on the
FZW
button just below the wavelength-entry window, and the
Device discoverer
window will pop up, listing accessible devices. Select
the
FZW
and the
FZW
measurements will appear in the wavelength-entry
window.
Note that
useFZW
must be set true in the config file (appendix E):
[wavemeter]
useFZW = True
Alternately, use the
-f
command-line option (see section E.1).
6.3
Calibrating with HighFinesse wavemeter
If you have a HighFinesse wavemeter, you can automatically load the
known wavelength from the HighFinesse measurements in real time.
Start the HighFinesse application and ensure that it is successfully mea-
suring your laser wavelength. Then click on the
WLM
button underneath
the wavelength-entry window.
