Dead on interpretation Red.Yes all my de-canned nugm03 diodes are still working too while I also have killed many multi watt blues after removing the GBall can.
From my research what I believe is happening is tiny particulate in the air burns onto the facet which causes damage to the protective coating used to keep moisture out, then after cycling on-off many times the moisture drawn into the substrate which is hygroscopic heats up causing fractures.....however this happens mostly in the multi watt blues, I suspect the 1w greens may not be as hygroscopic and/or don't reach the same damage threshold and the red substrate may not be hygroscopic at all as there are so many open reds and IR diodes.......anyway maybe the 1w greens which have an emitter size and divergence apparently similar to the 3w blues just don't reach the same energy density at the point where particulate falls onto the facet and thus avoid damage to the coating.......at any rate they seem to survive although it would be interesting to know how they stand up next to the window can versions used in laser show type projectors that get a lot of regular use.
I recently did some measurements with a homemade spectrometer. Oddly enough my NUGM03 @1.8A reads 520nm (dead on). I did my best to make sure the spectrometer is calibrated well with a 532nm DPSS laser, and was able to get the accuracy down to around +-2nm. Perhaps it's wavelength can be pushed higher if we over drive the diode with higher currents. But I doubt the wavelength would shift much, maybe 530 is the max.Did anyone measure wavelength on these? Read the thread and someone was to do this but missed the answer. I’d like to see if any are pushing 530. I miss that green. Really 540 is more what I want. That’s green to me. I saw the dpss 545 but diode 543 would be amazing.
