Description
IEC Filter Polaroid, Pair in Graduated Disc is an educational optical apparatus used to demonstrate the polarisation of light in physics experiments. It consists of two Polaroid filters mounted in graduated discs that allow precise rotation from 0° to 90° to observe changes in light intensity as the angle between the filters varies. Commonly used in physics laboratories, technical colleges, and engineering education, it provides hands-on learning of light polarisation and optical principles.
