Polaroid Filters Adjustable 90 Degrees
Product Code : JC-LOE-9416
The Polaroid Filters Adjustable 90 Degrees (SKU JC-LOE-9416) are a mounted pair of polarising filters, 50 mm in diameter at the centre, that can be rotated relative to each other through 90 degrees. On this mounted polarising filter pair with pointer and scale, a pointer moves round a circular scale and reads zero when the filters are aligned for maximum transmission, so the rotation either side of zero is easily measured as the transmitted light falls to zero at 90 degrees.
Specifications
The unit is a mounted pair of polarising filters, 50 mm in diameter at the centre, with a pointer reading on a circular scale from zero, at maximum transmission, to 90 degrees either side.

Experiments with the adjustable polarising filters
Because the pointer gives the angle directly, the mounted pair suits quantitative polarisation work, such as measuring how transmitted intensity varies with the angle between the filters.
- Demonstrating extinction of light by crossed polarisers at 90 degrees
- Measuring transmitted intensity against angle for Malus's law
- Studying the polarisation of reflected light
- Class demonstrations of polarisation with a single mounted unit
