To flesh out the thread a little more, I did some testing on a 784nm IR diode just to see what
would happen. As you may imagine, the trends apparent with the red diodes continued into
the infrared. I set the output to 150mW with the G-2 and then swapped out a few different
lenses. As usual, the baseline is the AixiZ uncoated acrylic.
650-G-1? Unknown source, given to me by polishedball - 38% increase over AixiZ acrylic, 165mW
G-2 from DTR - 25% increase, 150mW
AixiZ acrylic - 0, reference measurement, 120mW
Red coated glass 3 element - 4% reduction, 115mW
I don't have a G-9 to compare with, would not expect it to beat the 650-G-1, as it is coated for
blue.
