Abstract: An optical coating, such as anti-reflective coating (ARC) or colored coating for optical devices, suitable especially for mobile devices. The ARC is made up of alternating layers of low refractive index and high refractive index. At least one of the layers, preferably the top layer, is made up of nano-laminate. The nano-laminate is a structure of alternating nano-layers, each nano-layer made out of a material having refractive index similar to the layer it replaces. Optionally, each of the layers are made up of nano-laminates, such that a layer having low refractive index is made up of nano-laminates of nano-layers having low refractive index, while high index layers are made up of nano-lamonate of nano-layers having high refractive index. Each of the nano-layers is of 2-10 nanometer thickness.
