I want to simulate a real image captured by an infrared camera under an infrared light source illumination. The length of infrared wavelength is 850nm. How does we do such experimentation on blender. Is it possible to do it?

    $\begingroup$ What is the visual result you expect? Are you trying to achieve thermal imaging like effect, or one of those monochrome night-vision like images? Can you provide a few image examples of what you are trying to do? Either way that is probably best achieved in post production with some filter effects in the compositor nodes or something. $\endgroup$ – Duarte Farrajota Ramos Apr 4 '16 at 23:19
  • $\begingroup$ @DuarteFarrajotaRamos I did not talking about thermal imaging. I need monochrome night-vision like images. $\endgroup$ – BetterEnglish Apr 5 '16 at 1:19

Tristimulus models such as RGB are effectively a wide band visible spectral light emulation, making such experiments impossible.

Even spectral based renderers might have a hard time with spectral rendering when dealing with non-visible infra red or ultra violet, depending on how they have been designed.
