WTB> Binned 455nm+ diodes

[bloompyle]

I'm looking to purchase at least one diode binned for high wavelength, 455nm minimum. The higher the better.

That's pretty much it, very basic wanted thread

Bump!

Lookin for diodes folks!

Contact Angelos aka Lazerer since he owns a spectometer he might be able to bin a diode for ya! :beer:

The 9mm diodes and the PLTB450 have a higher wl than the rest of 445nm , I've probably seen 452nm reported somewhere on the forums, 455+ might be a little stretch.

455 is quite common, relatively speaking. RHD used to sell binned diode kits. I also know of at least one, if not 2 458nm diodes.

I only wish Angelos replied to PMs ....

O'Yes, Now that I remember rhd did had some of the binned high wl diodes. The power to wl trend was inversely related to each other iirc. Anyways good luck.

I can confirm 455nm isn't that rare. My Dominator "measured" 454nm on a "wall spectroscope". Of course that isn't precise but the color is still noticeably different to my older SL C6 laser - even to "non laser people".

Just chiming in because I'd also be interested in binned diodes. DTR could probably make quite a few extra bucks by selling them at a premium (say an extra 10% for each 5nm off), and he'd find a lot because he sells a lot The only investment would be the spectrometer and a quick test apparatus.

Send me a PM bloom. Got a lot of 445nm diodes on the way, there way be a high WL one in the batch

Here's the challenge with wavelength binning 445s -

To bin their highest wavelength, you need to run them at max current. You can't just run them at threshold current and take a reading. That means you need to press the diodes into modules, put the modules in heatsink, and run them as high as you're comfortable running them. That's not a deal killer, but it does mean that someone who sells a lot of bare diodes can't just wavelength bin everything.

Hadn't thought about that, makes the whole idea much more complicated :/
