Polarizer 2

  • Polarizer is a device which transmits only the component of polariztion parallel to its transmission axis. By using a polarizer, the plane of a plane-polarized wave can be changed; a circularly polarized or unpolarized light can be changed to plane-polarized.
  • When a circularly or unpolarized wave (natural light) is incident on a polarizer of whatever the orientation of transmission axis, the wave intensity passing through is always one-half of the incident one (after averaging over many random changes in the case of unpolarized wave).
  • No light can pass through two polarizers whose transmission axes are crossed perpendicularly.
    However, when a third polarizer is inserted between them with an angle not parallel to either of them, some light can finally pass through.
