Abstract
The present invention relates to an optical polarization effect demonstrating device. The device includes a first circular rotating polarization disk including a first main observation window and a first polarization film having a first polarization direction viewable through the first circular observation window; and a second circular rotating polarization disk including a second main observation window and a second polarization film having a second polarization direction viewable through the second circular observation window, wherein the first circular rotating polarization disk and the second circular rotating polarization disk are rotatably assembled in a concentric way such that the first circular rotating polarization disk and the second circular rotating polarization disk are rotatable with each other, and the first polarization direction is different from the second polarization direction.
