You may need to clarify that one. There is only one spectrum of light,
composed of its many wavelengths. Filters work by transmitting desired
wavelengths and blocking all the others, so that part is certainly
doable.
The light could then be recombined, but to what end? Are you trying to
create a true color image from red, green, and blue components?

If you mean, is it possible to combine data from various regions of the
spectrum (gamma ray, x-ray, ultraviolet, visible, infrared, and radio)
to
come up with a single false-color image, then yes, it can be
accomplished
digitally.




Thanks for helping me clarify my questions. Yes, there is only one
spectrum of light, which is composed of many different wavelengths.

Yes, I am trying to create a true color image from red, green, and
blue components.

I have taken the light from a telescope and separated it into Red,
Blue, and Green. Now what I am trying to do is re-combine all four so
that I have one color image. Is it possible to do this with a
mechanical device or could I do this with software? You said it could
be accomplished digitally. How would I go about doing this?

Thank you,

Dave
