The BLUE will reflect blue and pass red and green
The GREEN will reflect green and pass blue and red
The RED will reflect red and pass green and blue.
Red 615nm ± 15nm: Rabs= 50% (Will give you 50% reflection of those waveleghts)
640-750nm: Rave> 98% (Will give you 98% reflection of those waveleghts)
Blue 510nm ± 15nm: Rabs= 50% (Will give you 50% reflection of those waveleghts)
400-475nm: Rave> 98% (Will give you 98% reflection of those waveleghts)
Green 535nm ± 15nm: Rmax> 98% (Will give you 98% reflection of those waveleghts)
FWHM (R%): 65nm ± 15nm
Normally Green is the cheapest and most powerful (get as much green as you can afford) in RGB projector so it goes to the back of the chain. Then
goes red as second most expensive one. And then goes blue as most expensive. You need to preserve as much blue as possible. Green will loose about 20mw and red will loose about 10mw and blue only 5mw on the way to galvos. (I calculate based on 500red 400green 200blue)
I hired an Italian guy to do my wires. Now they look like spaghetti!
