Polarizer And Analyzer

A polarizer or polariser is an optical filter that lets light waves of a specific polarization pass through while blocking light waves of other polarizations. A polarizer or polariser is an optical filter that lets light waves of a specific polarization pass through while blocking light waves of other polarizations. 6 the device is often the same kind for both cases but in this context the polarizer is the device which sets the state of polarization of a light beam and the analyzer is the device which determines the state of polarization of a beam after it has.
