It is not in a finished state, but it is together and producing some nice colors. :cool: With the help of Pangolin's extra color channels and the ability to fully tweak the color settings, I got what I feel is a true purple. I have always loved purple and though blue magenta was a poor equivalent... ;) I ran a pair of wires off the 5th color channel and dubbed it violet. :D

I am using a reflect UV, pass all that I got from Mario Master to mix the 405. I have Bridge's dichro, but it is real thin and the dichro holder... won't hold it. I was in a hurry and saw that and grabbed it up. Based on "eye" tests, it is actually a bit more efficient than the dichro at the angles I have available in the projector. Once I have a meter on hand I plan on testing the loss on both of them. There is a fair amount of white loss and 405 pass thru on both unless they are at very severe angles. If you see in the pictures below, I go across the projector output to a mirror before going to the dichro at a 20 to 30 degree angle. Interestingly the sweet spot for both white transmission and UV reflection seem to be very close. I still want to check with a meter.

Some of you are somewhat familiar with the heavy beast, here are some shots of it with the addition of 140mW (after cube) 405nm set up. Right now it is running with:
140mW 405 daedal wdie4drives+, 4x@75mW, 6x@100mW, 140 after cube
100mW 473 Laser Wave
100mW 532 CNI
300mW 660 MechEng3 wFlexmods, 2x175mW, 300 after cube

:tinfoil:

Wow.
This is really the neatest thing i have ever seen posted in this forum :)
 
Very good color rendering on that allthat. I must say those are some of the best purples I've seen in a laser show. They just don't work as well without that violet in there.
