This question is posed to any litho people that have experience with state of
the art equipment circa 1970.

Does anyone know of a company that still makes a "photoresist camera" system,
where I could just purchase that projection subsystem of a photorepeater? I am
ideally looking for 1:1 projection, with a field of view, conveniently, of about
a 1" square or a 35mm circle would work too. Projection requirements would be
reasonable. Seems like something out there has existed in the past, but trying
to go through old Nikon Ultra Micro Nikkor catalogs doesn't mean I'll be able to
find anything out there today. I feel like this isn't too complicated of a
requirement, but I can't seem to find anything without going out and spending
quite a bit of money to have someone do a projection system from the ground up.

Any thoughts?

Thanks,
David Casale
