Thank you for posting those beam shoots, rep when I can. I just found your post, took me long enough to come across it. I'd love to see that beam up close.
You will love it even more once I manage to combine both beams with new 445/462nm dichro. Hope it works as expected, at least this is the plan.
"Preliminary tests" gave promising results. But I think this is only doable with 44 (maybe 7A75) and 07E. 05 and 08 WL would be at the Reflexion/Transition border. However, if at high currents they shift to 460nm emition, maybe Reflexion would prevail and they can be combined with 44s? About 06 I do not know at what WL gap it emits...
I am going to reassemble both devices and try other cylindricals, too.
Please look at the test pictures in the Reviews section.
Now I dismantled the blaster and changed both optical benches a little and here finally you have the picture when 2 beams (450+ and 465+nm) from two first pictures (already posted previously in this thread) are combined with Blue-blue dichro and directed into 3x cylindricals.
This is how 19W of blue single beam from 2xNUBM44 and 2xNUBM07E look! Well, there is a lot of waste glowing around, also...
In reality it was just an experiment, it is impossible to combine beams from separate benches perfectly this way for long. I plan to describe this in detail in Experiments/Modifications section.
