Thanks for the heads up, Alien.
From what I can find it is called "photon-enhanced carbon deposition"Maybe it's a combination of moisture as well as power and exposure to oxygen are all possible factors, but sealing it after being opened allows oxygen in, however maybe less moisture, depending upon the relative humidity when you did it, hmmmm....
Yes that does seem to be correct. Idential 465 marking on the back and all testing is spot on.My feeling is DTR's N465 is an 07E with a can, and the Nichia465 2.6W is from the same family as the NDB7k75, but 465-470nm :drool:
Yea that is pretty much nothing but an art collage cut and pasted together. Font for the NUBM07E is not the font they use as a standard in every datasheet and it says Engineering Sample which is from when they were still in development before any mass production has been done. Usually they accompany prototype samples to companies for them to start a commitment to make a production.I wouldn't buy this spec sheet as Nichi@ is famous for not releasing these and the Chinese are famous for patching ones together to make them look legitimate. This data sheet is not likely an OEM one.
Are you testing with only one current. Not sure you have seen but as you turn the multimode dioes up from zero to the max current some lines do go on and off and the picture looks like it might be parked on a perfect current where those lines fade at.While a couple different 07 diodes were still working I had noticed missing bars, I know other people have said the same thing.
Yep they really got their nipple in a twist over those or they finally had an actual example of a diode they say is counterfeit they can point to since they deny everything. I get people occasionally that say they called trying to buy direct and N!ch!a said the diodes don't exist like the NUBM44 block. Does not exist. Anyway that diode sucked. I was sent a small sample batch and I called BS on them in 30 seconds and pretty much threw them in the junk bin. I think they were some defective batch someone tossed or maybe they were an early attempt from some china factory to produce a laser diode based on some IP they took. I have never seen a 3 pin 9mm diode from them, had none of the usual markings or characteristics and the output patterns were not right some flickering in two of the ones I tested. I think the dye was mis mounted or something. Still have a few here somewhere. See if I can dig them up.While searching for info about a helium backfill I came across this unrelated but interesting page > Nichia Urges Caution in Avoiding Counterfeit Nichia Laser Diodes - LIGHTimes Online
