Boys juat let’s be clear, excuse the pun again, white light is made up of the colours of the rainbow- remember that in school, acually you need to factor in the UV and IR too, but that’s not for this discussion, the blue line is just a by-product of crap optics, nothing more nothing less.
I was joking when I suggested the blue dichroic- but I see Newman thinks this is a grand plan- now who has the brightest ricer headlamps- well move over rover let Andy take over- LOL.
And if you want more colours put a prism in beam and you can project rainbows- we could all go back to the 60’s- yeah baby…
Now I got my feet wet wading down through the snow to get to my barn, how do these FFFFing japanese things come apart???
