I got this setup now. ;)
The DICHROIC is from Edmund optics

The red/blue/green don't seem parallel after the galvos ;)

thanks people .

cruch, I prefer to have the red first. To me it's the one that I can afford to lose the most of... I have extra red though. I put my blue last. It is the most valuable to me. :rolleyes:

I prefer cruch's path, while it's true that blue is the most expensive per W so it makes sense to maximize it, I've found that people dig the reds more... A good red, orange or yellow gets gasps at shows so I try to keep my reds as bright as possible...

:sigh: It's amazing how much I REALLY want orange since I am only ttl at the moment... Is that normal? :rolleyes: If I could only get a analouge power supply for my blue and green. My MaxyMod is already good to go. :D Damn... I'd need a usb DAC for LDS also. :o

One of my greens is ttl, but if I change the colour attenuation in mamba black to maximum of 47 instead of the normal 255 it actually works as an analogue.
At 47 the laser is still on 100%.

if you like orange check out the two orange pointers i got recently

No... I want orange from my projector... A pointer may make that want worse AND cost more than buying an analogue power supply for both my green and blue... if I could fine them. :rolleyes:

I may be able to do something similar with LDS, but I have to get a DAC first... :o

Talk to Fred (Astroguy)... He can point you towards an analog PSU for your blue and green lasers.

My favourite laser colour is magenta right now.

Just looks so sexy.

Magenta is easy to make... You can do it with ttl. You need analouge for orange, and I dont have that, hence the want. :(
