⬅ Other Diode Tests Here are the test results for the NUBM06. You can purchase this and other diodes on my store. This one's results were surprising in terms of power. It surpassed most mid-tier diodes

The beam is extremely tight and concentrated :) Very good for star-gazing!

⬅ Other Diode Tests Here are the test results for the NUBM0E. You can purchase this and other diodes on my store.

Very cool! Thank you I wanted to order some yellow sticky paper for my laser printer to try this

I am only measuring the beam width (the high brightness part of the focused line)

You were correct in that the 2E lens clips off the NDB7875 fast axis! Remarkable. This is new to me. The G2 lens does not since it focuses so closely However my divergence measurements were equivalent with the G2 lens as with the 2E lens Real measured divergence...

I meant crystals as in the gallium nitride semi-conductors I see! Oh boy, I hope youre wrong so I dont have to run all those tests again 😅 Ill try this later with 3 diodes and see what we get :)

yess

Oh yes I plan to test all high powered greens. Not sure about violet or red yet, maybe in time

⬅ Other Diode Tests Here are the test results for the NUBM0A. You can purchase this and other diodes on my store. Very good power from this one ! 6th best diode in the line-up so far. The divergence is nothing to write home about though..

Current clamp or ammeter in series

Exactly

Yes, I do use the original brass holder which pushes up against the aluminium module. 14mm in length It even has set screw pre-tapped if you look closely

I measured power with stock Gball, decanned and then tested with G2. they were identical to the mW. Divergence without lens /= divergence with lens. This is because measuring divergence with a lens projects the laser crystal, and focuses it. Think of a diverging point source. Huge divergence...

I've got some S2+ heatsinks and drivers if you want Driver 4.2vin, 6vout, 1-2A adjustable

⬅ Other Diode Tests Here are the test results for the NUBM07. You can purchase this and other diodes on my store. A sweet diode if you want ~470nm wavelengths for relatively cheap and decent power to come with it! Make sure to give it the best heatsinking possible though

My pleasure folks! I do this for you guys The graph is to relative scale by the way I've added the 7875 data... wow. What a crazy tight diode!

The empty data will be added in the coming days
