My sense would be that for a lot of scientific imaging, you'd want to either
do wideband monochrome or narrowband monochrome, so a monochrome sensor with
filters would be what is wanted. All the metallurgy imaging I did (back in
the late 70s) was in B&W.

Again, scientific imaging has its own requirements that are different from
pictorial imaging, so it's not surprising that Bayer isn't the only game in
town in science.
