Well I tested the other diode for myself and to help anyone looking at these. Give back when I can. All the pics were taken with an older Olympus 500UZ which for some reason does a really good job with color differentials.
By the way, this is my Ophir setup on the top of my chest freezer that needs to be cleaned and the heat-sink used that I custom made quite awhile back soon after I started and no this isn't where I actually used them:
Yup, dual color
Was able to fit a different color panel on each side. I used to have a whole build thread on it but somehow it went bye-bye
It has various hookups so you can also use a MTM to read output with separate switches for Ophir and each individual LED. Don't need the LED's if using the MTM jacks. Wires off connector to diode went to my Variable DC power supply (duh):
Here's pics of the dot (with the GB lens) and after trying every different lens I had I realized that you do still have a bar but a lot less pronounced with a 3-element as expected:
I didn't bother with any shots of the first diode because it looked the same to me as my laserbtb 515nm 41mW regardless of output but I got lucky on my second diode This is my reward for the 9mm blowing. This one has a blue shift regardless of output
This is the only pic of the first diode that doesn't have the blue shift. You can tell when you compare it to the pic below as it looks like the laserbtb 515nm color on the left:
I crossed the beams and nothing bad happened lol
Those pics were taken obviously with the laserbtb 41mW 515nm on the left and the GB 515nm on the right which I set to the same 41mW. I could still see the difference in color even setting it to 100mW!
Plop-plop fizz-fizz oh what a relief it is
The diode sure doesn't seem to put out much heat at all and I once again took this one up to 360mA and it didn't show any issue. It also was more efficient than the other one using the same GB lens:
5mW at 47mA
30mW at 88mA
50mW at 122mA
80mW at 188mA
90mW at 217mA
100mW at 250mA
115mW at 300mA (I forgot to write down the 360mA one).
Was kind of in shock that it held it's blue green color with a lot of power. Now we cross our fingers that the one coming for Trend has a blue shift too. Hopefully some of you can also test for this but unless you already have a normal 515nm or a couple of the GB diodes to compare it might be really hard to tell. Will say that I used the 3mW 520nm that I had bought from Alex with the same setting against the first diode and there's a much greater difference between this blue shifted one that the difference between the first diode and the 520nm. It was VERY easy to see the difference in person but the pics did pretty good too although those are all laserbtb 515nm to blue shift diode.
I even swapped back to the first diode and couldn't see the difference between it and the laserbtb until I switched back to the blue one.
Haven't decided what to put it in yet and I don't feel in a hurry since I got pics taken.
By the way, nope, not selling it. I wouldn't care as much if it was only 5mW or less at that color but now it means a lot more.
Really hoping you guys get lucky too but I'm especially rooting for Trend as he wanted one with hopefully a blue shift at 5mW if I can get it set that low.
