Circular polarizer film questions

[s***@gmail.com]

Hi, just wanted to know where I can get circular polarizer film that is good quality. Also, is there any place where the manufacturing process is described?

Thanks,
Scot

The last batch I ordered was from Polaroid Corp, so I can't help a lot
there. ;)

Circular polarizer film is just normal linear polarizer film with a
broadband quarter-wave retarder laminated to it, on only one side. That
means that it passes one circular polarization, but converts it to
linear in the process.

If they had a second quarter wave retarder on the other side, it would
preserve the circular polarization.

Try American Polarizer

What wavelength? I've got old sheets of ~200 nm delay, good for 800 nm
1/4 waveplates.
