I have recently e-mailed a plan for a polariscope to a number of people
on this list. One of the materials in the plan is Polaroid J film. Two
pieces 7 and 1/2 inches square are required. The publication from which
the plan was taken is 30 years old. I have a couple of questions.
What is Polaroid J film?
Is it still available today under that designation?
Where can it be purchased inexpensively?
The Edmond Scientific consumer catalog lists polaroid film. It does not
specify kind or type, just generic polaroid. I suppose a phone call to
them might bring all the answers but I thought one of you might know.
