Abstract
SummaryOptical interference filter on polymer films ‐ Spectral channel separation in 3‐D projections by wavelength division multiplexingIn this work the preparation of optical interference filters on polymer foils for spectral channel separation for 3D projections is presented. The suitability of various polymer substrates for this purpose was investigated by measurements of the layer adhesion and the optical haze. Optimization of the energy input during the coating process and of the optical layer design offered a possibility to coat optical interference layer systems for spectral channel separation on PET polymer foil. It was possible to build working 3D glasses. Furthermore the application of gradient filters for the compensation of the spectral shift due to different incident angles and the processing of the coated filter foils were discussed.
