Linear Polarization Film Sheet A3 Size (297 x 420mm) – 90° Polarizer, Non-Adhesive – Removable Protective Layers on Both Sides

It is perfect item that I needed.

Adhesive not good product also vest of money dont nuy there is no minus rating otherwise its very bad

The product didn't mention the polarizing angle. I struggled to match the polarizing angle while repairing my LCD clock. Wasted a lot of film while figuring out the correct angle.I found out that the polarizing angle of this polarizer film is 45°.

No adhensive 😔😔😔 and small size price is too high 🥴🥴🥴

It was a wonderful experience to have this pair of linear polarized films. It can be used to understand and explain polarization of light.When one film is rotated relative to the other the light intensity is found to change and becomes almost zero when the films are perpendicular. It can also be used to explain Brewster's angle and Malus law. It also shows sharp decrease in intensity when used to view clear blue sky up head and thus explains polarisation by atmospheric scattering.Really happy to have this pair.Thanks amazon.

Filim is good with visibility.But it got burned and shrinking.

Pretty good for simple lab experiments. When crossed the extinction is good.

No refund
