Abstract:
A hybrid optical filter includes a plurality of film layers laminated to one another. This renders the filter flexible enough to be bendable and to implement a combination of at least two different wavelength-dependent optical filtering properties in a single hybrid optical filter. Two or more of the optical filtering properties may be caused by interference-based blocking of different ranges of wavelengths of light. Additionally or alternatively, at least one of the optical filtering properties may be an absorptive blocking of a first range of wavelengths of light and at least another one of the optical filtering properties is an interference-based blocking of a second range of wavelengths of light. The first range of wavelengths and the second range of wavelengths may overlap to provide for customized ranges of blocked wavelengths.
