High Finesse WS6
Control class to query and set the HighFinesse WS6 wavemeter. Heavily influenced by https://github.com/stepansnigirev/py-ws7 and therefore, this class should also be able to communicate with the WS7. Only tested with the WS6.
Preparation
Make sure you have the wavelength software installed and running.
You should also ensure that you know where the wlmData.dll file lives.
For a standard installation it should be in
"C:\Windows\System32\wlmData.dll".
Usage
For detailed usage,
see the docstring in the high_finesse.py file.
Generally,
the usage of the wavemeter class should
be similar to usage of any instrument
that is used in
InstrumentKit.
A simple example with comments is given below:
from high_finesse import WavelengthMeter
path_to_dll = "C:\Windows\System32\wlmData.dll"
# initialize the wavelength meter
wlm = WavlengthMeter(dllpath="C:\Windows\System32\wlmData.dll") # this is also the default
print(wlm.wavelengths) # reads all wavelengths in a listIf you want to interact with channels in switcher mode, e.g., to turn the third channel on, set it to auto_exposure, and read its frequency, continue as following:
ch3 = wlm.channel[2] # count pythonic!
ch3.use_channel = True
ch3.auto_exposure = True
print(ch3.frequency)Powered by
