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

Description

Circular Polarizers Film Polarizing Degree: 99.9% Dimension: 20x30cm/11.8x7.8 inches Thickness: approx.0.13mm. 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. 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. Attention This CPL circular polarizing filter does not distinguish between left and right rotation, so it is not suitable for 3D glasses applications.
