Polarizers are also called polarizers, polarizers, polarizers, or PL lenses for short, which are a kind of color filters. The excellent function of a polarizer is to selectively let light that vibrates in a certain direction pass. It is commonly used in color and black-and-white photography to eliminate or weaken the strong reflection of non-metallic surfaces, thereby eliminating light spots.
