Whats that software?
And i dont understand it now...
Theres not alot of blue in that picture.
And does that software work for you?

I had a topic in the red lasers forum some time ago and there i was also given a link to a brightness calculator. But i like needed 5w 658nm to have desame brightness as 500mW 532nm according to that calculator....

yes it works, to an extent.....it doesn't take into account different sized beams or divergence....


basically it shows you a theoretical white balance......do you see the small circle inside the triangle? That is your theoretical "white" from mixing the 3 colors at the powers you are have...




its showing that I need 4W of 655 to match my 1W green.....

Mrad is all <1 and beam size is max 3,5mm and minimal 2,5.
Pretty good if you ask me:)

You won't need to adjust the blue much, if at all. A "cooler" white is still white.

I ment ALL my modules are <1mrad and <3,5mm thick in diameter.
@cyparagon true but the best white is when its 100% white. For some good color mixing:)

Kgb could you tell me what that software is you are using and make a image for me to show how much i need to lower the blue power?

^ Agreed! Everyone makes a big deal about have equal amounts of Red, Green and Blue. If you have a 300mW green and +700mw blue pointer, try pointing them at exactly the same spot on a white wall. What do you get? A damn near-white dot on the wall. Mix in a bit of red and it looks very white. To the casual observer, they will not notice the difference!

In my RRGB projector I have 1.4 Watts of blue (turned down 50% in QuickShow), 1.5 Watts of green (turned down 50% in QuickShow) and just under 700mW of red (full on at 100%). I turn down the blue and green when doing graphic shows and I have a very nice RGB mix to work with and white looks damn near close enough. Then if I am doing a beam show in a very large room, I turn everything all the way up with a bit of smoke and it looks amazing! I have never had had an observer come up to me and say... "Hey! That's not perfectly white!" ;)

Es the eye indeed makes it look like a nice white. But when you balance it perfectly and then cancel that chance again quickly, you'l see how nice pure white you can get.
The difference is definatly noticable.

Only if they're next to each other, or you switch between them. This doesn't happen during a show.

White balance is HUGELY over-rated and overthought. One time Marc (CT Lasers) told me something that I've always remembered because it's the truth:

He said to only worry about bright beams. The brighter the beams the better. Screw white balance because the only person or people who will notice things like that are you and your crew. The people who might hire you or your friends if you do shows for them will always appreciate bright beams.

If you do primarily graphics it's a different matter... but by far most of a show company's work is beams, unless you're in a planetarium or something.
