Abstract

A layer arrangement (1) which changes the transmission of incident light depending on its temperature, where the layer arrangement (1) has a first polarization layer (5a), a switching layer (2) which influences the polarization properties of light depending on the temperature, and a second polarization layer (5b), whereby both the first polarization layer (5a) and the second polarization layer (5b) are arranged to affect polarization both in the VIS region and in the NIR region.
