3D Circular Polarizer Pair of Sheets - Left and Right Eye

This works excellently for 3D projection! No complaints. Make sure you have a proper silver 3D screen

These are plastic circular polarizer sheets, which is to say, they are a linear polarizer bonded to a quarter-wave plate. They are a lot easier to use than two separate plastic wave-plates.The problem is that they are not symmetrical. Light traveling through the sheet in one direction emerges with a predictable circular polarization, but if it goes through the sheet in the other direction, it emerges with linear polarization. These two situations are hard to tell apart, and you could easily get confused.(Similar comments if the sheets are used with a detector.)Overall, I recommend these filters. Working with them is a lot easier than using crystals or multiple plastic sheets.

I received two lefts, no right. or i receive two rights and no lefts. either way, the are the same polareization

These are definitely circular polarizer film. Only problem i had was part of the stick telling which was cut off a bit for the 135° polarizer film. The 45° stick was perfectly in tact but thought it might cause trouble if by chance both happen to be cut off some where it doesn't tell you which is which.

Pollination layer pulls off with the protection layer.

They work as they should. However, mine only had a protective sheet on one side of the film, and the unprotected side had a series of scratch spots in it.

I'd been using linear for years with my dual projector 3D, but these circular work just as well or better. I made a frame from corrugated plastic so the filters are a few inches from the projection lenses (5000 lumens!)... so far they hold up fine.

I’m working with linear polarization film, and this stuff is definitely circular. If you need circular polarization- you’ve found it.
