These are a pair of special Polaroid Filters with a scale printed on each. One scale is circular and degrees marked. The other is a simple cross for the alignment of one filter over the top of the other. Rotary displacement can be measured on the scale as the behaviour of the light transmission is studied. Size is 100x100mm. The thickness of the Polaroid film is 0.18mm.
