NUBM0G - 465-470nm Beast!






We can ask our Chinese friends to re-cap some with window cans and inert backfill, I expect they will anyway as long as these don't come at some inane increased price, being GBalls I expect they won't..... however there could also be a factory window canned sister diode.

What's the part number ?

Ah, is this them ?

Cool I ordered one to try out. :)

I'm weary of the whole "re-capped" diodes they have already. I've had the caps just fall right off so I'm guessing they may be stretching the truth on the inert gas part. The Chinese were also using these re-capped diodes in a bunch of engraving modules that failed prematurely.
 
Well, I was planning to use a c-lens pair to reign in the divergence, but I may have just bought a NUBM0C re-branded, this is why we need a part number for the supposed new diode that looks to be the same except it says 4.75W @ 3.0A rather than 4.1W @ 3.0A both say " 465nm typical " which may or may not be a factory spec.

Do we have the complete data sheet or a part number ?
 
A ton of new diodes recently appeared from some newer sellers and I question their legitamacy. Lasertree, sabzh21, opticsld and some of the other newer Chinese sellers on ebay are all the same company as far as I can tell. I asked "Ringo" from Techhood about them and he said they're in the same area near Techhood's office. I highly doubt that all these new diodes just suddenly appeared and that they're just branding the same diodes with different names. They're likely as real as the 5000W laser pointers and the 100 Million lumens flashlights that are commonly advertised...... Just my thoughts.

I have never heard of any problems with diodes from Lasertree, quite a few people on LPF have ordered from them and as far as I know nobody had any complaints.

Well, you just heard one from me. LOL.

Well, yes… 🙂 but are you certain those Chinese modules you were talking about had diodes from Lasertree, or were they just recanned from someone? Also did you have multiple diodes have the can fall off or just one? Having one defective unit is one thing but several and knowing of others that had failures is another thing..

Then you need to decrease the power output to account for adapting the optics if you want it adjustable or you can remove the g-ball lens and severely reduce the lifespan of the diode.

Around 4.4-4.65A should give you 7W of power these newer diode are more efficient. I'm awaiting half a block x4 diodes to do tests on them. I expect divergance to be really bad as per it's predecessors.

We have both part number and datasheet awaiting the correct time to post don't wanna have a bad reputation for incorrect information.

I'd be pissed at having just one recanned diode that fell apart on me.

Yes, I've bought from pretty much all the Chinese dealers at one point or another and I know which ones are more respectable. I'm not trying to brag but I probably buy and sell more diodes than 99.97% of the people on this forum so I'd like to think I kinda know what I'm talking about.

I chalk the losses up to R&D and don't really get mad about it, especially since it's tax write-off anyways.
