https://laserpointerforums.com/threads/ndg7h75e-532nm-cni-build.111271 Just remembered I have one of these lol. They were $260 earlier this year, assuming it's the same diode. Now that they are much cheaper I may get another for max beans

Very nice! How is the far field divergence compared to the stuff we are used to?

Those will be......energetic!

Lithium batteries, then sodium batteries, it was only a matter of time until potassium hit the table. I wonder how it stacks up against the other cell chemistries in terms of the availability of supporting materials necessary to make it into a battery.

^Even better!

Nice find! A little concerning that the picture shows the 28 LD array even though the title says 14 LD array which lines up with the OctoLas chart in the listing. 2 minimum order is a little unfortunate too 😕 I'm still hoping to see these pop up too

Any of you guys that buy stuff from Chinese suppliers regularly know a place I could source a NUGM32? The RGB array is sweet and all but I would like a 14 diode 12W green array. Or even the newer 23W NUGM35 would be awesome too.

Well this was unexpected

Yes, the reds are dual beam

It was $228 after shipping. I was a little hesitant to buy it considering the last time they came around they cancelled my order. Thankfully I did get a full refund

Thats kinda what I was thinking too, so maybe a 14 emitter RGB in the future. On a related note I found this neat little chart. It looks like there have been 465nm arrays this whole time and even a 532nm array in recent years. I bet 36W of 532nm is ungodly bright!

Has anyone managed to find the data sheet for the NUGM32T? I cant find anything. While looking back at the NUGM32T listing I noticed that the markings on the PCB traces say COM, RED, GR and BL. Is this thing a RGB array?

It makes a white blob at the focus point, nothing crazy useful

These micro arrays still amaze me at how small they are. I'm not sure how I want to set it up for long term so for now I have everything just mounted to a heatsink. Here its is compared to a 9mm diode The reds are dual beam diodes, not surprising but I was kind of hoping they would be...

^Holy crap! on mobile the ads are usually between two posts for me, I've never seen them injected into a post like that. Thats wild.

Not a single issue on the site when accessed from my computer, the site when viewed on my phone however is a pop-up nightmare! I still love this place though

https://www.ebay.com/itm/116251101984 12W green array, very tempting!

Has anyone gotten the double blue with both diodes in working order? I'd love to the see the far field overlap and how close they managed to get it

Nothing about it would lead me to believe its a fake but I don't have a genuine Sanwu to compare against. I'd say its a "real" one in the sense that it was probably made in the same factory that supplies Sanwu its lasers.
