Ok banged my head for a few minutes till I realized that my plan to mount both G's in the extended barrel might not work if I am right. I need to vary the distance between the two G's to get it to work unless I can find the exact perfect distance which would be a futile exercise.

I pulled out my stash of extra long lens barrels. I am going to try some different setups. For the backwards G and forward G do you have an estimate of the distance from G to G that worked for you? Would be nice if it was this easy. Sorry was actually trying to find one I thought I had...

Yea the NUBM47-A1/NUBM47-81/NUBM44-81 all test out the same slightly more efficient than the ones out of the older NUBM44-71/NUBM47T blocks. One note though as is usual efficiency and wavelength are inversely proportional. These are coming up lower in wavelength than the V1's from multiple...

Ignore the non existent case pin.🍺

Sure thing 🎅Ho-Ho-Ho Sure thing I do love playing Santa just hope I don't forget where I put it in 6 months.:p Made a nice vidde test as well. Added to the OP.😎

7W NUBM44-V2 450nm Laser Diode This is the most powerful laser diode that is known to be available as of 6/21/2019 Here is how the looks after being pulled from the NUB blocks. Here is the current king of the hill. The 6W NUBM44-V1(NUBM44-71/NUBM47T) is out of production for a...

Thought posted this relpy last night but still sitting here. Nice. That is a perk of the new site.... If measuring the same voltage between the power source and driver as is measured between the driver and the diode with no dropout thought the driver from the regulator then I would say...

Bumper, Sorry to see that.😥 It is common damage you see the with the blueray diodes. It has minor mirror damage in the cavity and not all the light is getting collimated properly. Some is escaping as stray uncollimated non coherent light. This light first shows as a kind of halo or giant...

EDIT: Did not see Chris had replied. Looks like you are already in good hands.🍺 I would browse around over on PL. A bastion of great info geared toward just the info you are looking for about scanners and show projectors. 🍺 https://www.photonlexicon.com/forums/activity.php

Tested the DTR-G-8 and it does not completely get rid of it but it is so faint you have know you are looking for it compared to the DTR-G-2 where you have to look for the dot as the box is 3x larger and very bright with this green diode. So I would put this in the win column for the DTR-G-8. Got...

I think they do have that rule but I guess they get away with it with accounts that are hard to prove are related or if you submit a complaint I have read in the forums that a lot of complaints on auction listing get ignored. They probably get so many that most go without looking into unless...

***TBD*** 520nm ??mW 3.8mm Single Mode Laser Diode """EDIT""" They are Sharp of course as there is an invasion of sharp lower quality diodes being sold as similar rated Osram diodes. So I get a few of new diodes here that was falsely being sold as PL520B. I have been testing which does...

Excellent write up. Package a lot of great info and insights in there. A great looking unit to boot.🍺 One suggestion though. I would toss out the idea of trying to figure a eye safe range for the fully collimated beam that could strike someone. Fist I would make absolutely sure there is not a...

If you think it might be the contact board is not making good ground contact via the ring which you can test several ways either via a dmm with a continuity test from the metal body of thee host and the negative wire going to the driver or if you don't have one you can always get creative and...

If three pin probably the one that had been selling as NDB7B77. https://laserpointerforums.com/threads/fears-about-new-diode.102624/ https://www.google.com/search?rlz=1C1CHBD_enUS829US829&ei=qY8KXajGBo6ytQWn9bDoDA&q=counterfeit+NDB7B77...

Great work getting it back up and running. Looks great. Good luck on the new project.🍺

BDR-209 has a QR code on the back and it also has a small dot over it. will get a better pic when I get a moment. Also you said it was a 3.8mm diode? Hard to tell for sure but looking at the size of the window in relation to the body made me wonder.

Yep just keep in mind that the unique qualities of this diode are that they are low in wavelength. The ones I had were also a SB14 model and they were already on the high side averaging around 509nm. Pushing them hard you start getting closer to the 515nm / 520nm diodes. They can certainly be...

Ok so it is a SB14 which should be case negative. Just wanted to make sure. Have not see the bin code 7F6. Started a sheet to try and map out what all the codes are and see if we can work out a pattern...

To make sure you get the right info can you give the number that is on the top of the can if not on the top of the can there should be one on the side of the can like these examples. The one on the side can be hard to see as at some angles. Almost hologram like.
