Abstract:
The present invention relates to an optical filter arrangement that have a cut wavelength for light passing there through. The optical filter arrangement comprises a stack of a first optical layer and a second optical layer. Further, the optical filter arrangement comprises an electro active polymer material arranged between the first and second layers such that the cut wavelength is adjusted upon application of an electrical voltage to the electro active polymer material.
