WebThe extinction ratio can be measured by directing a beam through a polarizer mounted on a rotation stage and onto a detector. Light polarized parallel to the transmission axis of the polarizer will pass through to the detector, whereas light polarized orthogonal to the transmission axis will be blocked. WebThe most common specification is the polarization extinction ratio (or contrast ratio), which is the ratio of maximum to minimum transmissivity. Simple sheet polarizers may reach …
