【Linear Polarizer】Polarizing Film is an optical film that allows a specific polarization of light waves to pass through and block other light. Rotating the polarizing film on demand and bringing an excellent polarization effect. 【Widely Applications】Physics education, LCD screen repairing, experimental, photography, etc. Meet your different needs. 【High Quality】Made of plastic material with high-temperature resistance, the polarized film has a high polarization rate of 99.99% and a high transmittance of non-polarized light, providing a clear display. 【Package including】It has two main forms: one containing only 2Pcs adhesive polarizing films, and the other including 1x polarizing film, 1x squeegee, and 2x wipes protected by cardboard. 【Tips for Use】After the polarizing filter is cleaned of dust, peel off the protective film and confirm the sticky side when in use. Adjust the angle, cut it into the corresponding shape, and stick it for use.Please note that the polarizing filter may not be suitable for surfaces with significant curvature, such as eyeglass lenses.
