I Polarizers and Analyzers in optics

  1. Mar 15, 2017 #1
    If we have a polarizer and an analyzer where the angle between the two axes is ∅ then we can find the intensity using Malus's Law.

    The intensity after the polarizer would be:
    (1/2)I0

    After the Analyzer we could have an intensity of:
    (1/2)I0cos2(∅)​

    What would happen though if ∅ = 0. Would the analyzer have any effect on the light intensity?

    In theory, no it would not. But that assumes ideal 100% transparency.
