Polarization analyzing apparatus capable of outputting light in analysis

摘要

The improved polarization analyzing apparatus comprises optical dividing member 2 which divides input light launched from an optical input section and an optical output section which supplies a polarization analyzer 1 with part of the light divided by the dividing member and which outputs the remaining light to the outside of the apparatus. A polarization controller 6 is provided in front of the optical dividing element and controlled in accordance with the polarization information from the polarization analyzer so as to retain a desired state of polarization.
