ABSTRACT:
A window construction adapted to permit or prevent light transmission including first and second fixed polarizer panels and a moveable panel between the polarizer panels comprising a polarizer and a wave retarder. The first fixed polarizer panel comprises adjacent polarizers which are in the same plane and have their absorption axes perpendicular to each other. The absorption axes of the polarizer panels are positioned so that maximum or minimum light transmission through the construction is effected by moving the panel including the wave retarder between the fixed polarizer panels.
