Polarizing Film - Polarizing Filter - Educational Grade

it works good , as advertised, 100% happy and recommend this seller

This was the exact fix my projector needed.😊

Used this to fix a Nelsonic Zelda watch with a bad polarization layer. (Didn't even realize they could go bad). It worked well enough - it darkened the screen just a hair, but the LCD cells are now dark and visible. The film was shipped in a flat, rigid sleeve, but still had a prominent warp to it, and the warp is still visible on the watch face. Giving this 4 stars because it did technically work, but dinged it one because now I have to spend more money on this repair trying to find another sheet that isn't warped.

i have my doubts about the polarizing. not work for me.

I ordered three for doing some fun experiments. None of them is even - all have some areas of different opacity. They do polarize the light but you feel like you are watching out of a dirty window because how uneven the polarization film is. I have know way of measuring but there is no way they filter out 99.9% of light (since putting two of them together at a 90% angle still feels like looking out of a dirty window). I have to deduce that EDUCATIONAL GRADE means it's low quality.

Worked great, did a School demo cut up and gave each child two sections.

Very good quality I fix lcd display from Tachometer for boat

Used it to replace the damaged polarizing film on an LCD display (happens to be on the remote cord set of a TroyBilt generator). Works great...I can now read the display clearly again at "normal" viewing angles.
