In Reply to: Fresnel lens for Super Graphic posted by Don Spangler on January 13, 2001 at 10:31:48:Don,
One source for a fresnel lens is Beattie they make a replacement
for the Graphic back. I have not had any experience with these
maybe someone can give us some feed back on these.
Their web site http://www.intenscreen.com/
has a dealer list where you might get some more information.
Also, found 2 sites with a running discussions on fresnel lenses,
interisting reading.

Hope this Helps
