Some weeks back there was a thread on film flatness with the Epson
1680 and 2450 scanners. I found this message from Jeff Mickey in the
archives.

Same here...I made my own holders. I use 8th..?..inch
presentation board, and tape the film carefully to the board. The spacing
above the glass is about the same Epsons holders. One caveat, at least on
the 2450, there is an aproxmatly 1 inch deep by 4 inch long notch that
is what the scanner uses to calculate exposure. It needs to be there :).

I am interested in fabricating some film holders for this scanner and
have a couple of questions for anyone who might have an answer.
1. Will the light cover an additional inch on the side to allow full
frame 5X7 scans?
2. Could one use a piece of very thin glass to get absolute flatness,
or is there some reason glass should not be used?
