Anyone on this group have any experience with removing the sensing
array from scanners and using it as an optical sensor? I'm interested
in using some of the old scanners that seem to be all over the place as
optical devices for spectroscopy, etc. Problem is that I have no
experience with these critters.

Assuming scanners are much like fax machine optics.
I once made a microfiche printer by extending a Fax CCD by wires out to a
scaled down traverse carying microfiche and torch bulb and a different lens.
The active CCD is about the same length/width (i don't remember which)
of a microfiche "page". Yes, a low level light source as you're not
illuminating 8 inches of paper.
Retain the rest of the electronics to process as normal
