Possibly stating the obvious, but...
Try turning the dichro around and firing the beam through the opposite surface. depending on how the lenses have been coated this may have an effect on performance.

Thanks for the thoughts
The angle is almost spot-on 45 degrees and the dichro has been tried both ways round, and currently has the blue reflecting off the coated surface.
It's almost as if the filter is polarized in some way (we haven't tried rotating the dichro) but I didn't think they were pol. filters...?
The Edmunds spec states for that dichro:
510nm ± 15nm: Rabs= 50%
400-475nm: Rave> 98%
Which indicates that it should transmit a large percentage of the green once your into the 532nm region, and the transmission curve seconds that as well.
Now I'm confused... I thought many others had used the Edmunds NT47-264 (or the 25mm diameter version, PN: NT47-267) to get the blue beam mixed with the yellow

That is the one I have. I just checked my order email. I don't lose that much. I don't have a meter, but at SELEM I think I was getting at least 90mW after the galvos off my 150mW lasever. I don't think it was producing 150mW either, closer to 120.
Hey guys, thanks for all the replies.. Think I might have a bit more testing to do...
I have now got it working, just a bit more fine tuning to be done, but here is its first attempt at scanning...
wow !
Eat Sleep Lase Repeat
looks cool, nice job
Looks great!
"Gravity its not just a good idea its the law"
Uh- yeah WOW! nice pics
I think I speak for everyone when I say "I want more pictures!" that looks incredible, I cant wait until I can afford my 457nm
