Maybe i could get those laser diode directly from japan,i probably have to buy a lot of them so i just want to know if some of you will be interested to buy some.It will not be cheap, right now i don't know the price.
fist it's not 400mw it's 500mw ,second not that much expensive because sanyo or sony created 12x there are a war betweeen the constructors, third very hard to contact the suppliers but it's in process
I don't hold out hope for these. You're looking at hundreds, if not thousands, of USD per diode. Buying diodes straight from manufacturers has been tried by people on here, and it has never worked out. It always comes out cheaper to buy the sleds, since the sled makers are buying diodes from diode makers in much higher quantities than we could ever hope to achieve.
These makers don't care much about selling 100 diodes, they care about BIG buyers. Good luck, but don't hold your breathe.
pullbangdead is right..Not long ago I attempted to buy a single 5mW 405nm diode directly from Nichia to see if their diodes are any different from the ones we see here routinely. Long story short, they didn't want to sell me one at all, and when I finally convinced them to sell me one (as an engineering sample) they quoted me a price of $2000 per diode.. no joke.
Needless to say, after a hearty laugh I hung up on them..
