Calculate the transmitted light intensity through a polarizing filter using Malus's law. Determines how much light passes through when polarized light encounters an analyzer.
Enter your values below
Intensity of the incident polarized light.
Angle between polarization direction and analyzer axis.
How this calculator works
Malus's law states that when polarized light of intensity I0 passes through an analyzer, the transmitted intensity I depends on the angle theta between the polarization direction and the analyzer axis.
