There has been some talk about "vaporware" 510nm green diodes.
They do exist (I have a vision on the M & M's TV commercial).
It seems also important to have a photo posted of the diode- not sure how much value that will add.
Anyway, the wavelengths on the green diodes is steadily increasing as time goes along. This makes sense. Mature 405nm, 445nm diodes moving up in wavelength for GaN devices. 510 nm is lower cost and premium diodes at > 515nm are 5X the price. Picoprojector companies want higher wavelengths, as many of us want higher power, higher efficiencies (lower operating current), etc. Well it's out of the lab, and does not need Liquid N2 to operate.
To put it in perspective, green diodes sales/ samples are very tight right now. Many manufacturers have developed diodes that are either not released yet, or developed for medical applications where diode prices are $4K. Other diodes that are in the sample status are like Gold in 1850's; everyone wants their hands on it. Reverse engineering is a big issue, so as a distributor, I can't sell the diodes without the manufacturer's knowledge of the end customer's name, application, etc. One does not want a diode to end up in a competitors lab. It will happen, maybe, but that's what's going on. I have signed a Non Disclosure/ Non- Reverse Engineering agreement, and my modules can not be sold at this time. Diodes can be sold to end users upon approval. That's the black of it. The grey of it is there is a market for occasional diodes to end up here and there by someone who has one, can get them in Europe, etc.
So anyone out there that needs green diodes for production, let's talk about it. Otherwise release of green diodes will be slow for hobby use. OK after parts are mark as Released/ Production.
I hope this sheds a little light on the subject. I may review this post and edit this when I look it over again. Late Wednesday here.
