yes my harshness was not poised at jem...it was poised at those manufactures. sorry jem if I implied you, I too am aware of the angle problem...thats why I want it SOLVED!!!

Been there, done that, got the t-shirt & selling it in a garage sale.
Ahhh... You have such a delicate way with words Pat
No offence taken at all, and I know what you're getting at. I was merely pointing out (for those who weren't aware) that angle tuning can improve things somewhat .
Interestingly, even the custom 'Semrock' dichro, which is supposedly a top notch piece of kit (and custom made for us), requires angle tuning to get the best out of it.
Once I get myself a new camera i'll post some pictures of my projector re-build that Rob (Stanwax) did for me. You'll see from the pictures that some strange angles are employed to get the best out of the dichro's.
Cheers
Jem

Hi Marc,
Would you be so kind to test again with 45 degrees.
Myself in multiple projectors and many other people got way different results at 45 degrees!
I'm loosing a crap load of red through the blue dichro.

Just out of interest, what wavelength red?
I am about to use the LW 25mm's

I think the Laserwave dichros got a good price/quality ratio and a nice mount.
But they are definitely not the best dichro's, if you are looking for high quality dichro's with low losses I would look further, I know I will for my next RGB build.
You can also read in Insanity's "monster" RGB tread how big the losses are.
For quality dichro's try:
Pritzler
Swislass
Kvant
But expect to pay more...

Hi Marc, did you had a chance to test at exactly 45 degrees?
As you can read in this post I have 15% loss of red trough the blue dichro.
