Miss B, the whole thing is based on an old BB thread for dispersion in Firefly I read some years ago. Might have been RDNA but I had thought it was here. You would do the same thing in Blender but with a colour ramp node you could increase the "fire" to include the entire spectrum in addition to the three primaries shown here. Add more wavelengths (colours) to the shader shown above by adding in more of the modular blocks. Glass, Glossy, Refraction. Any of those nodes can fake the dispersion. Refraction is the "correct" method as that is the physics that produces the effect in reality.
More good info to know.
