Very interesting, Ralf. That's in my to-do list, now I'm digital-eyed.
But there is a long way...

The Wratten #87 is an extremely strong IR filter, totally opaque to the
human eye. It is way beyond the sensitization of the usual near-infrared
films (Konica IR795, Ilford SFX200). Apparently, the DS' IR sensitivity
extends to much longer wavelengths (820+ nm).
Enjoy,
Ralf
