:coffee: Had step away and give Aug a hand with some orders before he had to get out to the post. That is one thing every one direct sourced brand new units will have. IF there is no attempt to conceal the source then it has passed a retail sale and no longer the liability of the manufacturer...

On these they are new and a lot of TBD data. Like every new diodes from this manufacturer the only thing that I am confident in is that the block they come out of(not the diode part number we will probably never now that) is NUGM03. You can take the datasheet as a it being in the ball park...

Yea don't do this. It is the drivers job to provide a fixed current at all times when the power source is in the listed range. These are buck/boost drivers and a linear and buck can be pushed out of current regulation by limiting the current demand the driver is trying to draw but I have noted...

You know now I think of it I did not offer those NDB7675 20mm 2.7A overdrive units for very long as they went out of stock after maybe two weeks of offering them and did not relist them any of the times they came back in stock but I had sent out maybe 15-20 of them even with the big warning...

You are not kidding. I spent probably 50X more time on trying to learn than I have so far actually using the one I got. So far I am really good at cutting the back off the brass 12mm hollow back halfs to make sleeves for diode presses.:rolleyes: I was actually mostly interested in being able to...

I have been trying to get them back. I keep pushing but no luck yet. It is possible the situation could change but does not sound like it will be anytime soon. They do seem to have more appeal over the N!chi@ display based diodes for lightshow projectors. Few of my customers that manufacturer...

These are cute.:p Seriously as paul said some details would help understand what you are working with and trying to do. Every diode has specific requirements for operating current and forward voltage which will determine what configurations of power source and drivers will work as well as...

I am working on organizing my next production run of modules and I had been wanting do a small batch of the 25mm or 20mm mounts maybe both with a larger threading to accommodate larger diameter lenses. Some lenses out of a group funded projectors way back I did with Lazeerer and Daguin who...

Here is something interesting I found the other day when digging around the net from Osram. It has a lot more info than standard datasheets as well as a section with detailed info on suggest ways for designing laser drivers when using their diodes. Goes over what they consider needed features of...

No problem. Mostly copy/paste from something I had been working up and just a good timing. That is not odd. They current draw will vary and the math to try to use it for useful calculations is not feasible. Any change in the source voltage or voltage being droped by the load will have a fixed...

You will want to use a test load to set the current. A laser driver puts out a fixed current always as long as it is being powered as per the specs of the driver in the case of the LDSE500 is 2.9V-9V and the source can deliver all the current demand the driver is trying to draw from it which at...

Oh no.:cry: I a am pretty sure it is toast. Two Li-ions in series are up to 8.4V when fully charged which is too much for the unit and it looks like it is no longer lasing with that blank area dividing up that the faint line output . That unit with driver is 2.5V-6V input. If going battery...

Here yo go. Also resized for a little easier viewing. ;) I will reply here as this is something I have strong opinions on. Your observation was 100% as on topic. I embrace it as it added valuable insight for this lens giving people the actual info to know what to expect which they get very...

Crazy. These sharp 488's do seem immune from the DTR-G-8's Juju magic.

Strange it was the sharp 488's that I had when I first tested the DTR-G-8. Will go back to one and see if I am getting the ghost box with it. I Made a little setup for testing out of 75 feet with each lens measuring the fully collimated spots length/shape/size I want to do with all the diodes...

Great thorough review as always.🍺 Started eyeballing some spectrometers recently so I can add some more details to my testing threads. Thanks for all the details. Lot of great info to absorb when I get a chance to go over it all in detail to get familiar some footing on them. Should motivate...

Sent out quite a few so far with 700mA ACS1500SE's. So far have not had any reports of failures yet but it is still early. Hopefully that holds and if it does given time will bump up a bit and give it some time to generate any failure data. I do sell to a pretty wide range of customers and the...

That spring is much safer on this than the one pictured in the OP. The only picture I see of the side where I assume the output pads are you did not take a picture of the whole board. I assume the case pin of the diode goes to the pad at the top of the side you pictured three times for the case...

That would be awesome. Look forward to seeing the results.🍺
