Is that the 3XBE adaptor for the Striker that you are using in this pic ? If so that's great that it's threaded on the inside as well.





The standard adaptor that screws onto the M9 x 0.5 lens barrel is in this pic

I have almost a dozen of the 3X beam expanders like these 2 of mine, I use them with threaded heat sinks and with the lens barrel adaptor like this pic

I think that long adaptor may be the Striker adaptor, that's what I was asking because I will buy some if so




---EDIT---

Ok I see there is the standard adaptor and a stainless adaptor, but not that long inner threaded one.

no its not from the striker,this is only the adapter that sanwu selling with extra 5$ with the beam expander,i just use an empty barrel to screw it on the end of my final focused beam
if i use the 3x beam expander i have lower divergence than a 7875-7675 diodes with G2 lens and that with final output of 4,5w+ of 455nm and thats why i don't have any problem to use a gball diodes as is if they got interesting specs,if the new diode can be pushed to 7+w that mean i could have nice divergence from it with 5w+ without decanning




edit:with expander on it look like this

Says nubm49 which is one up on the 48/44-A1?
The description says "Absolute Maximum Current!!!! = 5A!!!!"
Maybe not with the exclamations, but still.

Possibly as stated earlier, just a canned 44 in a bigger bin for the huge projectors.

or could be a diode in the 44 power range with a bit higher wavelengh(450nm+)

Interesting use of single aspheric lenses and three element lenses to refocus ball lens diodes. I haven't seen anyone successfully accomplish this until now. I'm out of rep at the moment, but will get back to you, deadshadow.

thanks paul :) billy i would buy this diode for testing as its not expensive but the problem is that im getting the items from china over a month later which there will be already a tests of someone else at this time.

That’s all good, I usually recieve items in 2 weeks from China, There has been other promising and interesting diodes before that as far as we know here still haven’t been purchase so unless you know someone is buying one to test, a month might be fine!


They did list only 5 left I think, This is the 10,000 lumen NEC I was thinking of Anyway! Out of our price range!

No way to know for sure what diode is in this "new to us" block till one is tested properly to get some data on them as there is very little chance the ones sourcing/pulling them know anything about them either. Could be same diode as in other NUB blocks. One thing that I think is important to note the block number does not give us any indication of the diodes model number that is in them. It is a reference to full block package. Same diodes have been seen in multiple units as in the 44/47 and different diodes in the same main model number on those blocks with the secondary number being the only change noted when the diodes changed was the 71 to 81 on the 44 and T to A1 for the 47 going from the V1 to the V2 NUBM44 as we refer to them.

I do have thoughts of them being pulled from used equipment as that is a very common in China right now and the price is just not working out. There are so much misinformation on these blocks going around as it is but I can make some guesses with simple math. The price they are selling, how many diodes are used in similar units to make X amount of Lumen and the range of cost for those projectors new even if buying in bulk/wholesale. Several units with 5000 Lumen laser only light source use two NUBM05 blocks. That is 16 diodes. This had 19. What projector if they are claiming new could possibly have more than 5000 Lumen could be purchased for say $300-$500 per 5000 lumen(maybe a multiple bank projector) or so which is just an estimate based them selling for $850 after fees, shipping, markup and a buffer for the occasional loss. Here is a pretty comprehensive list of laser projectors over 5,000 lumen.

Projector Database: Projector Feature Search

to be economically feasible I am thinking based on the cheapest unit out there in the 5000 lumen range you would have to be albe to buy them for 1/5 MSRP.

They could be sourcing them some other way but I do see some grey compound on them so they do look like they were actually installed in a machine.

Based on what they are saying if they are not quoting an actual rating which I doubt they are as most diodes will do almost double their rated output when pushed(which is how they get the 20,000-30,000 hours life ratings) but the listing says it can push past 6W but does not suggest it as it overheats. Sounds similar to what the NUBM06 diode can do with a ball lens.

hi Jordan,
And thank you for the input clarifying these diodes. I t was just a matter of time for you to give the correct analysis for these diodes.
Thank you for chiming in and giving a more clearer light on the subject . Always appreciated for your words here on LPF.

Rich:)

This 525nm could be interesting although I would like to see some new window/can diodes. They do brag about a gold color bottom, as in not sealed into a block with indium foil, yet they are tin pin, would that mean they are from the big replaceable projector blocks ?

They list diodes as BRAND NEW, NEW-OTHER, and REFURBISHED, so there seems to be some differentiation, I would expect BRAND NEW to be nothing less, these are NEW-OTHER.

The data sheet they are using would suggest these are like the NDG700s. I'm not a buyer.
