The subject of projected image differences in Kodak Pagaent projectors
with different kinds of optics comes up here now and then. Could someone
(Alain? Sam?) explain this in more detail, for those of us who are curious
but not so well-versed in optics?

What is a condenser lens? What is its function?

Is this something one just finds on Kodaks, or on other makes of
projectors as well?

What models of Pagaent do or don't have this design?
