I've seen them in approx. 8X10 size. They can be found in office supply stores along with the magnifying glasses.

Dumb question time. It's probably already been said, but I can't remember. If mounting a fresnel behind the ground glass (on the outside) toward the rear of the camera (and not between the glass and lens) does the lens part of the fresnel lay against the glass or away from it?

See the following:

'Grooves must face the light source in this application' (p. 8).

And lots of other stuff.
