Linear Polarization A3 Sheet Polarizer Educational Physics Polarized Filter Optical

High Contrast Linear Polarizing Film featuring excellent extinction ratio and high transmission. Ideal for a range of imaging applications, teaching experiments and more. Available in sheets, can be easily cut with scissors to fit any application need. Linear Polarizing sheets are used in experiments relating to birefringence, light scattering, polarized light experiments, light reflection, Brewster's angle and how polarized sunglasses work. IMPORTANT(!) please note that on both sides there is a protective film sheet. You have to remove it gently before use. Once removed, the polarizer sheet will be revealed, clean and smooth. Common uses: 1. Get two of these (or cut one in half) for an excellent classroom demonstration of aligned and crossed polarization filters. Aligned, two pieces have about the same effect on unpolarized light as one piece. Rotate them and at 90 degrees, no light passes through (quite black). 2. Great for taking the glare off tattoos for photos 3. Use this to dim a LCD screen that has no brightness adjustment option 4. Cut down the glare paintings while photographing. 5. Use this sheet to modify your microscope and polarize tissues. 6. Use the polarizer to remove flash. 7. Use the polarized sheet for our security camera that's facing out a window to remove the glare off the footage 8. This is being used to control/minimize specular highlights in a photography application.
