Every time a component of the monochromator (MC) is adjusted (light source, input slit, output position, etc), the feed from the MC requires calibration anew. 

The Python scripts used in this calibration are included in the InstrumentScripts repository of the Stubbs lab: 
https://github.com/stubbslab/InstrumentScripts/tree/main/sampleMonochromitorCalData 

Calibrating MC requires three steps

...

We detail an example below.  In this example, we use the StellarNet Inc Black Comet spectrograph, which we calibrate with the Ocean Optics KR-1 calibration light source.  Future re-calibrations of MC should be able to can use the same calibration of the StellarNet spectrograph, which we include in the GitHub repository with the calibration scripts:XXX sampleMonochromatorCalData directory. 

Here are the steps in our example:

STEP 0: If running this analysis on a new computer, you must download the StellarNet drivers for the black comet spectrograph. See the Black Comet Instrument Page here: Here is how:

1. Download the SpectraWiz software.  The version for Windows 10, downloaded on 03/17/2022, is available on the above GitHub repository.  Various versions also available at the StellarNet website: https://www.stellarnet.us/stellarnet-downloads/ (Serial num of Black Comet is 18042612).
2. Useful instructions from StellarNet are available here: https://www.stellarnet.us/wp-content/uploads/Spectrometer-Installation.pdf Additional steps/notes are:
   
   1. Step 1: When you execute the file as administrator, the program will say something about PnPutil.exe not being recognized.  That is okay.  Move onto Step 2. 
   2. Step 5: after running the SWUpdatezAP-Install632 script as administrator, you may get an error popup that says something like "run as administrator failed".  This is okay.  See if the StellarNet spectrograph has shown up on the desktop.
