PE, this is probably mostly for you but of course others are welcome to help out.
As an optical engineer, I'm pretty particular about spectral data. So searching for the spectral response of base silver halide doesn't leave me very satisfied with the results I find on the internet or in my references at home. I've seen spectrographs from 100+ years ago, but surely measurements were performed in the intervening decades to higher fidelity (like a vertical log scale). Silicon detectors, for example, are very well-characterized and the spectral response of undoped silicon is readily available showing response out to 1150nm at which time silicon becomes transparent. I could draw that response from memory (as well as InGaAs, HgCdTe, etc) just from working for decades with imaging systems. But for silver halide ... just a vague "sees UV, Blue, and negligible response beyond that" .. whatever negligible means.
So I'm curious, could you direct me to a source for quantitative spectral response of silver halide? I'd love to see the whole UV/VIS/NIR spectrum. If I had that info, I could do some radiometric calculations which I'm playing around with.
