My 'Little' 532 projector project is now finished

Output was checked through a 45 degree bounce red dichro at 45 degrees.

not sure if those would block any of the ir

They perhaps wont block it but they do reflect it. Well, the same dichros do on my 473 and 532 in my RGB projector anyway.

If you use a bounce red or pass red dichro the ir is most definitley lost. If you fire a green laser with no ir filter at a laser-wave GBR dichro for example (pass red bounce green/blue) the faint green dot that passes will measure a stonking value on if you point a lasercheck at it and view the same dot with a ccd and you will see a green spot haloed bay a pink glow. Most certainly ir.
I cant say that all dichros do this but the Laser-wave ones do. This is why in my opinion the effects of ir in the output beam can be considered negligable when using LW dichros.
