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

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
