Note that
useWLM
must be set true in the config file (see appendix E):
[wavemeter]
useWLM = True
Alternately, use the
-w
command-line option (see section E.1).
6.3.1 Multiple HighFinesse wavemeters
HighFinesse wavemeters require a separate installation of device-specific
software for each different HighFinesse device. If you have installed more
than one on your computer, the default
wlmData.dll
may not be the
correct version for the device you are trying to use. In that case, copy the
correct
wlmData.dll
file to the
mogwave
installation.
The
wlmData.dll
file is typically in the
Com-Test
folder of the HighFi-
nesse application for the device you will be using, for example
C:\Program Files (x86)\
HighFinesse\Wavelength Meter WS6 1234\Com-Test\wlmData.dll .
Copy this to C:\Program Files (x86)\MOGLabs\mogwave\mogwave .
From time to time, HighFinesse change the way they store and load
wlmData.dll
, and the above may not work for your system. Contact
MOGL abs if you are having difficulty.
6.4 New wavelength range
Reconfiguring the device to operate at a new wavelength, outside the range
of the imaging sensor, is a quick and simple process.
1. Remove the top plastic cover and the bottom aluminium cover of the
device.
2. Loosen the
λ
screw holding the diffractive optical element (see be-
low) for Rev 1 and 2 devices (serial numbers starting with W1 and
