520nm diode that can go as low as 510nm ?

I'm hunting for 510nm and it seems there are no affordable options in the market other than buying 520nm hoping it will be <515nm

So I wonder if targeting 5mW output which diode will be a suitable choice to achieve at least 515nm and possibly 510nm ?

I'm sorry if this has been discussed somewhere, I've been away from the hobby for the last few years and my knowledge of such stuff is quite outdated.

The diodes in this area of the spectrum are generally of the same construction. The range is generally 510-520 for these diodes, so depending on the way you drive it and temps, you should be able to get pretty close with any of them.

O$ram plp515nm or the n!chia 515 offer on dtr laser shop
Why are you obscuring their names? Is that something I should do?

HI,DL.
I built a 510nm small host some time back, 510nm is a great WL The color is sweet at that WL. Hope you can find a diode there pretty rare at 510nm flat out but they do exist and i'm not talking about a 520 or 515 running on a lower setting. Heres a few pics;;

So now the options are narrowed to either Osram PL515 30mW or Nichia NDG4216 100mW.

Are there any spectrometer readings of these two diodes?

Nice build you have there, is that a 510nm diode ?
