Hey Boris, I ordered one of these nubb13t to try out, the initial spacing between each beam center is 1.25mm where the nubm35 is 2.4mm and the nubm31 is 3.5mm, I will make a post when I get it and post a pic of what the alignment looks like.
If somehow the alignment is reasonably good, then knife edging a few could be fun.
Great. I'll wait for you to share how it is when you get it. I am these days waiting to receive the new NUBM35, I hope it works because they tested it beforehand. You know what the case was with the previous one.
Hi everyone -i done this laser 1 weel ago -it use NUBM31T brand new laser diode 95W 455m -driver input 12V -output is 3A 85V -i use fan to make heatsink better,you can hear when you see video -laser have a key lock,1 switch turn laser and other turn fan Now i will show you some detail pics,video...
Just got a nubb13, it's a lot smaller, only 1.25mm from beam center to center.
The beams are closer together to start, but the divergence and the spread is no better than one row from the nubm35's
The focal length of the gang lenses on the nubb13 appear to be shorter which makes sense as it's a thinner package as well as being smaller overall.
The spot on the left is the nubb13 and on the right is one row of 7 from a nubm35 distance is about 10 feet.
I received the new laser array today. Fortunately, everything worked perfectly without any problems. It is set to run at 4A and definitely impressed me with its power compared to the previous one which was broken and only 6 diodes working
3.5A is the max on paper with a good heat sink to get the rated 20,000 hours lifespan, now the diodes will take 5A but I wouldn't push them that hard because they are so close together, not without TEC active cooling, plus you would get diminishing returns as heat builds up quickly, so at 4.0A you may not get 20,000 hours but it's a trade off for max output.
I won't raise more than 4A. At 4A the laser works great and is very powerful. I'm even still amazed at his power. Even if I asked for 10,000 hours, I would never reach them. This is for playing with it though, not working with it. Things worked out very well with this lens. I made a video with her
This thing cuts through some pretty thick sheet metal
