This set of 2 polarizing filters is designed for use with the Eisco Labs Optical Bench Kit (PH0652). Each filter measures 5 inches long by 3.75 inches wide by 1 inch tall and features adjustable polarization for demonstrating how light interacts with polarizing materials. Ideal for physics and optics classroom experiments studying polarization, malus's law, light wave behavior, and the orientation of electric field vectors.
