Thin Film Plate Polarizer
Product Description
A polarizer is an optical filter that passes light of a specific polarization and blocks waves of other polarizations. It can convert a beam of light of undefined or mixed polarization into a beam with well-defined polarization. The common types of polarizers are linear polarizersand circular polarizers. Polarizers are used in many optical techniques and instruments, and polarizing filters find applications inphotography and liquid crystal display technology. Polarizers can also be made for other types of electromagnetic waves besides light, such as radio waves, microwaves, and X-rays. Our typical specification:
