Polarized Film Sheets 3 PCS 8 x11inches/20x30cm Polarizer Linear Polarizing Filter Non-Adhesive for Educational Physics Photography Lighting

Works well for my purpose in a light box, the images are good, it cuts easily and fixes well with various tapes. It is worth the money.

Holding one sheet horizontal and the other vertical blocks the light well, I used it to make a polariscope. The type I bought had two protective films, one on each side and isn't sticky on either. For me this is a plus as it allows me to use them as boundary layers to sperate small, loose, lightweight types of films.

This polarized film is thin enough to be cut easily with scissors. Crossed sheets produce good dark background. The sheets are suitable for use as the polarizer on a light box, but unfortunately the sheets are matt on one side, so no good for use as analyzers

Damaged the polarizing filter on my resin printer LCD screen, so needed to replace it, used this. Works perfectly, a lot cheaper than buying a new screen for £120. Also these arent' self adhesive but I managed to get it to stick well enough using a bit of soapy water and some tape.

Dont purchase this, the protective plastic layer does not peel of easily and the polariser splits as you are trying to remove the protective coating. The plastic protective layer is too thin to peel and just stretches and tears.
