Polarizer Demonstrator - OS-9477A
Demonstrate the effect of crossed polarizers with these large round polarizers.
Product Summary
These large (19-cm diameter) polarizers are perfect for polarization demonstrations. Each polarizer has a rigid plastic frame that has angle markings in 5° increments. The polarizers can be hand-held or fit into a stand that allows the polarizer to be easily rotated by hand. Malus’ Law can be quantified using the Polarizer Demonstrator and a Light Sensor. The angle is read directly from the polarizer. 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 polarization an amount that depends on the wavelength of the light, add the Polarization Demonstration Accessory (OS-8172).
