Crossed Polarizers. In Figure 18.17 below, three polarizing disks whose planes are parallel to each other are centered on a common axis and the direction of the transmission axis of each disk is shown relative to the common vertical direction. 01 An unpolarized beam of light is incident from the left on the first disk with an intensity lo. Malus' Law states that the intensity of light that emerges from two stacked polarizers is given by I(0) = 1, cos' (0) , (18.6) where O is the angle between the polarization axes of the two polarizers (for example, in Figure 18.13, the angle between Polarizers I and II is 90). When unpolarized light falls on a single polarizer, the transmitted light is reduced in intensity by half and it is polarized in the direction of the orientation of the transmission axis of the polarizer. In the case of three stacked polarizing sheets shown above with unpolarized light incident on the first polarizer, Malus' Law gives I,=1, cos (02 -0,) cos (@, - 02).
