Hi Rick...
Yes.. All powers will add-up , minus maybe 5 to 20 percent depending
on the size of the Trichro/Dichro.
The bigger..the more loss you will have.
I have one here about a foot in diameter..Its HUGE.
Just be real careful of backreflections as I believe the coatings
are broadband.
And were originally made to work the other way around, of course.
But they do work in a pinch rather well..!!!
We have been using about 30mW of green with our 200 reds.
and about 50mw of blue (its all we have at the moment)..
Most of all ...Good luck and have fun
