    """take_image: The function will create a Operating System timestamp variable (OS_time), configure

    Parameters:

Example #2

single_cam_mono_sweep
Created on Wed Dec  9 13:12:18 2020

This script will sweep over wavelength on the monochomator
for a single measurement configuration.

This includes image capture for a single camera (no MS)
And a single polarization state (unpol, H,V, ect)
Output will be saved as a hdf5 file 
Uses flirpy, make sure enviroment is open
uses python-usbtmc
