Ah - I thought the readings would be taken one at a time, it would indeed be a problem if they were at the same time.

I am in need one one that can measure <0.2nm resolution.

Meatball, hopefully someone from UNL can hook me up?
I think the one I used is capable of .01 nm resolution on the high count grating. I'll have to ask around to see if someone else is currently using it or not.

I'm taking a break from research. ;)

The problem I had with mine is that the lines were so close together the peaks combined into one slightly wider hump, so although it had a peak in the 609nm region the multiple HeNe lines were not distinguishable.

This should be doable though with a high line count grating though. You lose total nm span but you could easily get down to the hundredths of a nanometer.

I ordered my grating from edmund optics, it was about $80 all said and done.
Also when we separated the 609 line, your meter read it as 594 :p

Though that could have been sleep loss resulting in me separating the 594 line itself, and we didn't catch it due to it being 0130 :p
