This is not at all unusual. I do have a stock of microfilm reader
lenses, if we can figure out who actually built the reader and which lens
it takes. Is there a name or model on the lens or reader (other than DEC)?

Thin plastic is really unusual here because of the tendency to melt under
the heat of the lamp.

This is exactly what my company does (and my previous, now defunct,
employer as well). I have dedicated microfiche and microfilm scanners.
The problem I ran into when trying to scan my DEC microfiche collection was
that the fiche themselves were of very poor quality. Badly scratched and
scuffed, and poor quality duplicates.
Jim mentioned that dedicated microfilm scanners are expensive. He's not
kidding. Used machines tend to start around $5k USD for a low end, heavily
used scanner. New machines are generally $30k at the lowest end. Flatbed
photographic film scanners are much cheaper, but also slower. However,
with some scripting and tools like the ImageMagick library, you can scan an
entire fiche in one pass, then slice up the image into individual pages
