Luenir Circular Polarizers Film 11.8x7.8 inches Circularly Polarized Filter polarizing Sheets for Photography, Educational Physics Experiments,2 Pack

Idea for Photography -- Polarizing Film is to reduce the polarized reflection of a non-metallic substance in a certain direction. For example, glass, plants, water, skin, tattoos, ground table tops, exposed sky. Wide Application-- Circular polarizers are also used in optical science experiments, teaching physics experiments, and experimental light blocking. Tips for Use -- 1. Peel off the protective film on the polarized film 2. Rotate the polarizing film clockwise by 360 degrees to find the right angle of reflection. Circular Polarizers Film -- Polarizing Degree: 99.9%. Dimension: 11.8x7.8 inches/20x30cm, Thickness: approx.0.13mm. Attention --This CPL circular polarizing filter does not distinguish between left and right rotation, so it is not suitable for 3D glasses applications.
