These large (19-cm diameter) polarisers are perfect for polarisation demonstrations. Each polariser has a rigid plastic frame that has angle markings in 5° increments. The polarisers can be hand-held or fit into a stand that allows the polariser to be easily rotated by hand. Malus’ Law can be quantified using the Polariser Demonstrator and a Light Sensor. The angle is read directly from the polariser. Any light source can be used, but the experiment works especially well with the Color Mixer.

To demonstrate optically active materials that rotate the angle of polarisation an amount that depends on the wavelength of the light, add the Polarisation Demonstration Accessory (OS-8172).
