These are a pair of special IEC Polaroid Filters that are 0.18mm thick, 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.
Instruction sheet included.
