## Description

Specification: Polarization: Linear，Greater than 99.9% Size: 21x15cm Thickness:0.22mm Feature: Polarizing film have protective film on both sides, before you use it, you have to peel a protective film off the front and back. Educational Application: Work great for class projects to demonstrate the effects of polarization in a very affordable way. Physical Experiment: Linear Polarizing sheets are used in experiments relating to birefringence, light scattering, polarized light experiments, light reflection. Photography Filter: Use to reduce the glare caused by smooth surfaces such as glass, water, paper, and certain metallic objects. Package content: 3 x Polarizing film sheet

Review: Great to show mind-blowing STEM science - Here's a simple STEM experiment that will defy most folks' predictions. Step 1. Attach first piece of the film to the window with painter's tape (see red rectangle in picture). Discuss how it blocks some of the incoming light, because light acts like a wave, and has an orientation. The film can be thought of as having vertical bars, and thus only the portion of the light that is aligned with those vertical bars makes it through. (For purposes of the experiment, describe the light that passes through as having "vertical" polarization.) Depending on the experimenters, you could draw a unit circle, and explain why ~50% of the light passes through the first sheet. Step 2. Temporarily place the second piece of the film at the same orientation as the first piece. Discuss why it doesn't block much more light. (the light that passed through the first piece was polarized vertically, so a second layer of "vertical bars" won't block much more.) Step 3. Slowly rotate that second piece of the film to the window until it's at a right-angle to the first (see blue rectangle in picture). Discuss why it's now blocking essentially all the light. (Light after first piece is all vertical, so there's no horizontal part to the light ... while the second sheet is now only allowing through the horizontal part, which is zero). Step 4. Tape that second piece as shown in the picture, making an "L" shape with the two pieces. Where the two pieces do not overlap, ~50% of the light will be passing through. Where the two pieces overlap, there will be ~0% light passing through. Step 5. Temporarily place the third piece of film on top of the other two pieces of film, as shown (green in picture). Discuss the amount of light that ends up passing through at each place. A. where 1st+3rd or 2nd+3rd films overlap: ~1/3 of the light is passing through (as expected) B. where 1st+2nd films overlap: ~0 of the light is passing through (as expected) C. where all three films overlap: ~0 of the light is passing through (as expected) So far, so good. Typical stuff that many high school physics classes have shown. This is where it will get WEIRD, and VERY non-intuitive results will occur. Step 6: Ask what folks to write down what they think will happen if, instead of the third film being layered on top, it was placed ***BETWEEN*** the first two films. Specifically, would the amount of light passing through anywhere change much vs. it being layered on top? Step 7: Slide the third film so it goes between ... and enjoy the expressions of bewilderment, curiosity, and disbelief! That's just AWESOME ... it's like a magic trick that takes no practice. It boggles the mind! Enjoy!
Review: Eliminate reflections from a textured surface - I need to take some images of my son‘s paintings that he does on textured canvas. Using flash or studio lights creates a lot of reflection in the textures. I took one sheet. I put it on horizontally on the right light as the other sheet was put on the left light vertically this eliminated all reflections on the paintings. Sure beat the heck out of Photoshoping those little white dots out of the paintings.

### ⭐⭐⭐⭐ It does what I supposed to.
*by R***A on July 29, 2024*

I use it for polarizing light coming out of lamps for photography. They work. Not the best quality you could expect, but for the money, they're decent. The polarizing effect is as expected.
