Dimension: 11.8x7.8 inches/ 20x30cm, Thickness: approx.0.2mm. | Scope of application: communication equipment, automotive electronics, household appliances, instruments, measuring instruments, and other dashboard display products. | Tips for Use: 1. Peel off the protective film on the corners of the polarized film and confirm the sticky side. | 2. Clean the screen of dust and debug the angle. With the screen as the center point, overlap the sticky side on the screen and rotate the polarizing film clockwise by 360 degrees. Find a clear position, mark it well, and then cut the polarized film to the appropriate size and paste it. | Package Details: 3 x Adhesive Polarizing Film sheet. There is a protective film on both sides of the polarizer, please tear off when using.

Linear Polarization Angle:0/45/90/135 Degree. Dimension: 11.8x9 inches/ 20x30cm, Thickness: approx.0.12mm. | Scope of application: communication equipment, automotive electronics, household appliances, instruments, measuring instruments, and other dashboard display products. | Package Details: 4 x Adhesive Polarizing Film sheet. There is a protective film on both sides of the polarizer, please tear off when using. | Tips for Use: 1.

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.
