I just got a great deal on a Bentham M300 monochromator and am trying to learn how to set it up.
I'm pretty sure I found a table showing wavelength against counter readings for a given grating ruling, but I'm struggling to find it again. I've run the dial through its range with a white light source and I can see the full visible spectrum, so I do at least know I have the correct grating for visible light work.
Does anyone have the data I need to conver dial readings to wavelength?
