Online calculator or program for additive color mixing?

[Laser57]

I want to mix the output of a pair of 460nm and 520nm laser diodes together using a PBS cube, but don't know the shade of cyan the mix would produce, is there an online calculator, or software which will let me put in the wavelengths of two colors I want to mix in nm and display the resulting color?

that would strain your monitors color gamut

I was concerned about that too.

I am still looking for an online additive color calculator, but I need one which will run on my Apple computer.

If both same power and I'm not wrong resulting additive is about 490nm Cyan (on eyes perception)

There was a nice software called "Chroma, laser color blender" once here, developped by a member, but the first link is unfortunately dead... Maybe if you have time to look through the entire post you would find another download link or so

Thank you, also having Diachi at LPF look to see if he has it on his HD somewhere. I was hoping it might allow adding three wavelengths together, two I can easily figure out, but three I could use a calculator to get a better idea of the shade.
