Does anybody
still do the very early photographic glass plates?
about 35 years ago, a friend of mine was doing sandbox holography. She
went in to Alpha Photo in Oakland, which was one of the few real
professional supply houses, where she bought her supplies. They had
different glass plates than she was used to using (dimensional stability
was too critical for film), so she asked about their suitability for
holography. The clerk said, "Don't know. But we have a customer who is
really expert about that, and I'll find out!"
When she got home, there was a message on her answering machine.
"Hello, this is Mike from Alpha Photo. We have a customer who wants to
know about glass plates for holography, . . . "
Speaking of which, . . .
Does anybody have need or use for a Fujinon table-top Holography System?
(from the 1970s, barely used, but needs a new laser tube. NO, a pocket
laser pointer is not suitable. Power supply is multi-tap, currently set
for 100VAC (Japan), about 24" x 18" x 14")
Free Pickup in Berkeley; I don't want to attempt to ship it.

*Hand-drawn* holograms. Yes, really. Quite astounding.
