wow never really thought of that, how true!Blows my mind the difference in 7 nm in that part of the spectrum. You can go from 632 to 660 and almost not notice unless side by side
Wherever there’s a crossover band there are greater changes in wavelength perception. Yellow and cyan are very narrow parts of the spectrum.Sweet lasers! Would love to add a couple of those to my collection!
I've always noticed that in the blue-green part of the spectrum, just a tiny difference in wavelength is noticeable. I have two "488"s of the same power and I can tell that one is ever so slightly more to the green side. Probably only a few nms at most. The same small difference in the red end of the spectrum I find is almost unnoticeable.
