Well,
I don't see a 589nm beam in my near future, mainly because it's unlawful to import - and Frankly, I just don't want to deal with that right now.
I was considering metal-printing a mount to create a simple red+green combining module, throwing a dichro in, and calling it a day. Can still get it handheld as well, at the appropriate outputs.
But then I thought... We have all sorts of options for greens now, and a couple options for reds. Obviously summing two different, non-coherent and most certainly mis-phased, Mis-TEMed, wavelengths doesn't change the optical harmonics of two beams, which are already barely interacting with eachother... But, to the human eye... Does anyone know what the best combination of red+green diodes would be to achieve that 589nm yellow?
Or just an equation in general? Or, a concept in general? There are all sorts of interesting colours I'd like to make some small, weak pointers with... Not currently achievable with solid state diodes on the market, or at a reasonable price.
