ABSTRACT:
Optical device has a carrier substrate with a surface consisting of a plastic material with a predetermined index of refraction and with first mechanical and/or chemical characteristics. The surface is coated and the coating has second mechanical and/or chemical characteristics which are different from the first characteristics. The index of refraction of the coating is different from the predetermined index of refraction of the carrier substrate surface material, varying steplessly through at least a part of the coating, up to the end index of refraction and the surface of the coating.
