Zusammenfassung:A filter comprises a support substrate. A film is disposed on the support substrate, the film comprising a polymer matrix material and a filler. The filler has a particle size distribution configured to filter a desired range of wavelengths of light, the particle size distribution having been achieved by extrusion. An extrudable composition is also disclosed. The extrudable composition comprises a polymer matrix material and a filler. The filler has an average particle size ranging from about 1 nm to about 700 nm and a concentration ranging from 0.001 weight % to 0.3 weight %, relative to the total weight of the extrudable composition.
