Polaroid Filters Circular Scale
Product Code : JC-LOE-9415
The Polaroid Filters Circular Scale (SKU JC-LOE-9415) are a pair of 100 x 100 mm polarising filters with printed scales for measuring how light transmission changes as one filter is rotated over the other. In this polarising filter pair with a degree scale, one filter carries a circular scale marked in degrees and the other a simple cross for alignment, so the rotary displacement can be read directly while students study the polarisation of light. The polarising film is 0.18 mm thick.
Specifications
The pair consists of two 100 x 100 mm square polarising filters with 0.18 mm film: one marked with a circular degree scale and the other with an alignment cross.

Experiments with the polarising filter pair
Placing one filter over the other and rotating it shows the transmitted light falling from a maximum towards zero at 90 degrees, and the degree scale lets students record the angle for each observation.
- Demonstrating the polarisation of light with crossed filters
- Recording transmitted brightness against the angle of rotation
- Investigating Malus's law with a light meter
- Observing polarised light from reflections and display screens

Frequently asked questions
What size are the filters?
Each is 100 x 100 mm square, supplied as a pair, with 0.18 mm thick polarising film.
How is the rotation measured?
One filter has a circular scale marked in degrees and the other a simple cross, so the angle between them can be read as one is rotated over the other.
What should a quotation request include?
Send the SKU JC-LOE-9415, the number of pairs and the delivery destination.
