  • Circular polarizer film questions

    From scotbohnenstiehl@gmail.com@21:1/5 to All on Sun May 27 14:03:10 2018
    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.

    Cheers

    Try American Polarizer

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