This 3-piece set of non-adhesive linear polarizing film sheets is designed for professionals, educators, and DIY enthusiasts who require high-quality optical filtering. Each sheet measures 7.8 x 11.8 inches (20 x 30 cm)—a standard A4 size—and is 0.19 mm thick, making it versatile for cutting, shaping, and applying to various surfaces without adhesive residue. With a 99.99% polarization rate and a 90-degree polarization angle, these films deliver exceptional performance in controlling light transmission across the visible spectrum (380–700 nm). Key Applications Physics & STEM Education: Perfect for classroom demonstrations of polarization, Malus's law, stress analysis, and optical principles. Use in labs or science fairs to teach wave theory and light behavior. LCD Screen Repair: Replace damaged polarizing layers on LCD monitors, smartphone displays, tablet screens, and other digital devices. The non-adhesive design allows easy placement and alignment. Photography & Lighting: Act as a polarizing filter to reduce reflections, enhance color saturation, and manage glare in studio lighting, camera filters, and window coverings for photography setups. Optical Experiments & DIY Projects: Suitable for building polariscopes, creating privacy screens, anti-glare displays, and custom optical devices. Use in research, prototyping, or hobbyist applications. General Purpose Filtering: Ideal for artistic installations, light polarization tests, window tinting experiments, and educational kits. Technical Specifications Package Quantity: 3 sheets of polarizing film Sheet Dimensions: 7.8 x 11.8 inches (20 x 30 cm) Thickness: 0.19 mm Polarization Angle: 90 degrees Wavelength Range: 380–700 nm (visible light) Polarization Rate: 99.99% Material: High-transmission linear polarizing polymer Adhesive: None (non-adhesive design for flexible application) Why Choose Our Polarizing Film? High Optical Performance: Achieve deep polarization with minimal light loss, ensuring clear, high-contrast results in any application. Easy to Customize: The sheets can be easily cut with scissors or a blade to fit specific sizes—ideal for custom screen repairs, small device displays, or experimental setups. Durable & Reusable: Made from robust polymer material, these films resist scratching and can be handled repeatedly for educational or prototyping use. Versatile & User-Friendly: Suitable for a wide range of users—from students and teachers to technicians and photographers—thanks to its non-adhesive, easy-to-handle format. Value Pack: With three sheets in one pack, you have enough material for multiple projects, repairs, or classroom activities without frequent reordering.
