Educational Innovations Polarizer 6x6 in. Plastic Polarizing Filter

I'm using this filter for my microscope. Happily, it's much thicker than I expected. Very durable. It wasn't easy to cut a circle with a compass circle cutter, so I finally resorted to scissors to finish the job.In view of all the negative comments, I'm wondering if the people who made those comments were aware that this sheet of polarizing film comes with a protective sheet of film on it, which has to be peeled off. The sheet I received came perfectly clear without a mark on it. During the handling of this sheet, many hairline scratches and marks appeared on the sheet, but these were actually on the protective film. Once peeled off, the polarizer sheet was shown to be in perfect condition.It works as advertised. Rotating one piece of this polarizing filter in front of another piece, does indeed vary the light that gets through, from allowing the maximum amount of light, to total blackout. I was very satisfied. An excellent product

Very misleading image of product - You get ONE not seven . . .I think this is a deceptive misrepresentation of what you get.The text does not give the number . . . but the image implies more than one.Furthermore . . . It does say:These 6 x 6-inch, high quality plastic polarizing filters are perfect for all kinds of experimentation.When I went to school, THESE was the plural for THIS . . . AND it says filterS . . .Amazon . . . take note.It went back. I was annoyed at myself that I fell for the deception.

*Be sure to remove the protective film from both sides before use*I have prescription glasses with the blue light filter. This causes my eyes to be obstructed on my webcam by strange floating squares.A quick reddit search showed that polarizing filters could be the solution I was looking for!I cut off a small square of this filter and removed the protective film.I wedged the filter in front of the camera piece on my webcam.Bye, bye blue eyes!The only thing to be aware of is that a this is a filter, it will considerably darken the rest of the output from the webcam. An affordable solution is a cheap clip-on ring light :)

It’s true what they say says 6 sheets only got one but only really needed one so not mad, value for money for me is good, quality is good cause it did what I wanted it to my screen doesn’t shine on my glasses any more on camera and the image remains perfectly clear. Oh and do make sure to take out the film protection or it’s not as good.

It's polarized, 1 square sheet. It apparently got bent in the process of being made, packed, delivered, or something so one spot Is distorted but these things happen.

I recently purchased an Anker PowerConf C-200 webcam. It was great but I had an awful glare on my glasses from the computer screen. The C-200 has an oddball "square-round" shape and there are no snap on filters available. I ordered this filter and cut a piece to fit, then taped it on. You do need to test orientation to make sure the piece you use is lined up to cut the glare. Then cut it out with scissors. I only needed a piece roughly 40mm square, so still have a lot of the sheet for another project some day.

La imagen es engañosa, parece que vienen más en el paquete pero solo es uno 🤔

We used these for the optics unit of AP Physics. Very useful.
