Phill,

Scary really, the one I disassembled had a haze of extremely fine particles 
coating the mirror, much like the haze in an old lens.  I'll have to 
reevaluate some of my film developing conclusions since I use the scanner 
to determine things like relative acutance and edge effects from 
developer/film combinations.  Hmmm.
