RA;
Did you try the Hi-Power lens on your 808nm diode ?
Is has the largest aperture possible in an Aixiz lens assembly,
which is a factor with IR bar diodes.

I thought about this, but >2.0W is a lot to pump through such a small (and expensive) lens, and I wasn't sure if the coatings would be able to handle it (they are for 405-650 right?). I figured 808nm might be too far out of the range. Maybe I'll give it a try on my latest 600mW 808nm burner.
I still have to finish the darn thing anyway, I still have yet to get a mount the diode and optics.
I may have another job for you MISTERWILLING.
I killed my 6x in testing so I can't report any comparison to acrylics on that, but I was getting 200mW @ 205mA for all of 5 seconds.
With green (IR filtered), I get a very low loss (120mW avg without lens and output varies between 117and 118mW with lens).
This test was done just by putting the lens in front of an already collimated beam so I cannot report how well it works for collimation and focusing.
