[Not quite true. Konica 750 has a "bi-modal" sesitivity curve with one "peak" at something like 550um, and the other "IR" peak at 750um. Both peaks are uniform (they look like semi-circles) so there is an amount of sensitivity out to ~ i don't know .... 850um or so.]

You guys are slipping. I mistakenly labeled the wavelengths as "um" - or "micrometers".... Ooops!! Should have been "nM" or "nanometers". Not much of an error ... only one thousand times (1000X).
