An antireflective coating suitable for use on polymer optics

Although metal halide anti-reflective (AR) coatings are widely used by manufacturers of electronics equipment, high application temperatures mean that they can only easily be applied to glass substrates. Screens made from plastics materials can be coated but the process requires additional steps to prevent damaging the substrate. A new, easily applied anti-reflective coating has been designed which can be applied to both plastic and glass substrates. The single layer coating applied to an acrylic substrate has proven to be better performing than current commercial single layer anti-reflective coatings. This performance has been achieved from an amorphous fluoropolymer solution which is dip coated onto the substrate.
