Multilayer refractive index (RI) tuned film is a great demostration of Nanocomp’s technological and productional capabilities. It combines microstructure imprinted film with refractive index controlled material and both of them represent the competitive advantages of Nanocomp. Multilayer refractive index tuned film has two refractive index layers with functional microstructure in between. The whole process is compatible with Nanocomp’s UV roll to roll imprint production.

Key benefits:

  • Highly functional component reducing the bill of materials
  • Enables using standard integration materials and process
  • Optical functionality is hidden and protected from surroundings


  • Displays
  • Sensors
  • Lightguides
  • Waveguides
  • Other optics


  • Available refractive index range n 1.4 – 1.6, allowing effective refractive index difference between layers up to 0.2.
  • Substrate materials: PET, PMMA, PC
  • Widths up to 500mm
