Take only photons of a given color

    Hello all. I'd like to make a "machine" that recognizes the color of a photon. I'd like, then, to take just photons of a given color (or of a given range of colors) and then send them to a PSCN-NSCN, so that it sparks. Also, other photons must be sent away, not deleted. Is it possible to do it?

    It might be possible using glass, as different wavelengths(therefore, colors) are treated differently in glass. This is also how one of those PHOT-thermometers works.

    Chech this out for an example of how it may work

    Thanks, but I actually I need a very small tool. The "machine" will be implemented into a sensor for a camera, so a big sensor means a low resolution.

    Well it was an example, im 99% sure it's possible to make one small enough for what you're doing.

    I made a sensor like that, but it's still too big. The glass isn't "sensible" enough, so the sensors must be placed at a certain distance - too much, anyway. I'll resign myself to b&w photos, which - however - is still a rare thing in TPT (there are about 3-4 WORKING cameras, all of them are b&w).
