Polarizer,also called polarizing filter,abbreviation of PL.It includes Linear Polarizer and Circular Polarizer.An absorptive polarizer filters out the unwanted beams by absorbing them, and leaves behind just the desirable ones. The most common type of absorptive filter is a wire grid, which allows only a single type of beam to pass through.
Polarizers are most useful for increasing general outdoor color saturation and contrast.
