556 vs 561, visible difference?

[laserboySweden]

Hello! I am about to purchase a 556 or 561 nM, but I can't decide which one. Anyone who has seen both of these wavelengths IRL? Is there a (significantly) visible difference in colour? Or are they pretty similar?

Thanks a lot,
Filip

They both should look yellow-green and you would only be able to tell the difference if you place them side by side. Where are you getting them from by the way? Also, are you looking for one of those as your first laser?

The difference in color will be very small, most likely not enough to recognize a difference.

If you do end up getting one, watch the duty cycle

I agree with the above statements, 5nm difference is just enough to see but it's not much and I am not sure everyone could even see the difference.
