Mix wavelenght calculator ?

[pyrodigy]

Dear Experts
I will have a couple of questions. I would appriciate any thoughts and comments .

1- Can i able to find out what color at what power would i get after mix two or three laser wavelenghts at various powers ?
I mean is there any formula like this;

A.watt 445nm + B.watt 532 nm + C.watt 650nm = D.watt ....nm ?

Wavelenghts would be 445nm, 473nm, 650nm, 638nm, 532nm...etc
Powers;
445nm or 473nm will be between 3W to 15W
532nm will be between 3W to 8W
637nm or 650nm will be between 1W to 3W

2- What is the easiest method to have 473 nm from 445 nm?
Do i need to add some green to 445 nm or need quality 473 nm Dichro in front of the 445 nm?

Yours faithfully

If you start out with three discrete wavelengths of light then your mixed result will always be some combination of only those three wavelengths.

The resulting color might appear to be of some other wavelength, but it will still be a mix of the original wavelengths.

Pure HUE is obtained by mixing no more than two of the red, green or blue lasers together. If you mix some amount of all three colors you get White or a TINT of a HUE. White or anything close to it will never be found as a discrete wavelength on the spectrum.

If you pass a mixed color beam through a prism, it will split back into it's original discrete wavelengths.

Human color vision is a very weird thing!

This has ben automated already.
You can search the forum for "chroma" software.

Thank you very much for your comments.
I have just downloaded Chroma. Look pretty good.
