2 Sheets PET Linear Polarized Film Sheets Rectangle Black 300x200x0.4mm for making

Optimized Size for DIY: 11.81"x7.87" sheets (0.016" thick) balance portability and functionality, easily trimmed for screen repairs or classroom demonstrations on polarized light, glare reduction, and light refraction principles Black Film for Enhanced Experiment Precision: Reduces glare and ambient light interference during physics education setups, photography sessions (e.g., glare-free shots of glass/water), and scientific research requiring controlled polarized light environments Widely Compatible Polarizing Film Sheets: Ideal for repairing LCD screens on phones, tablets, monitors, TVs, and devices like car dashboards or ATV displays, offering universal fit for diverse screen sizes and models with precise alignment and adhesive flexibility Premium PET Material for Optical Clarity: High-quality PET film, low light absorption, and durability against scratches, perfect for crisp display restoration and physics lab experiments Teaching Experiment: It can be used with flashlight, laser pen and other light sources to carry out experiments in a darkroom environment, so as to make the polarization effect more obvious. It can also be used to observe the screen of mobile phone and the blue sky with a film, so as to deepen our understanding of polarization's life
