The K&F CONCEPT two-ply polarized film uses Nitto polarized optical film, which has professional-level polarization performance and a polarization rate of up to 99.99%. It measures 7.8x11.8 inches/20x30cm and is 0.21mm thick. It has an adhesive side on one side and a non-adhesive side on the other, and both sides have protective film. (Please remove the protective film from the adhesive side before use.) A scraper and dry wet cloth are included to improve application and prevent air bubbles during the application process. There are "red" and "blue" marks on the surface of the polarizing film, with the red sticker side being the adhesive side and the blue sticker side being the non-adhesive side. How to use: After removing dust from the polarizer, adjust the angle, cut it to the appropriate shape, and stick it on. (⚠️Rotate it 90 degrees to make the film transparent or opaque.) Polarizer protective film applications: Suitable for experiments and physics learning, such as motorcycle meters, small LCD screens, optical equipment, and smart watch screens. Physics Experiments: Linear polarizing film can be used in experiments such as birefringence, light scattering, polarization, and light reflection.
