Thanks for the link, I used to harvest them from sleds, but did not know they where available as a bare diode.

The 660nm wavelength is a killer though, you need shitloads of power to get a visible beam.

Not a terrible prospect to knife-edge a few given the cost.. Also, I prefer the deep crimson of 650-660nm over the slightly orange color of 635-640, but that's only personal preference.

When we find an effective and affordable solution to this blue diode I think we should do a group buy for the 250mW 640nm Optnex diode.
It is the same price as the 150mW and has better beam specs than these blues.
What ya think?

the 150mW, I understand the 250mW got higher divergence and wider emitter, so less suitable for a multi diode setup.
These aren't a bad deal on 638nm for the price (~$320US): http://www.mitsubishichips.com/Globa.../200907/02.htm
