Abstract
Method for producing novel diamond bodies having near-surface areas of reduced index of refraction which act as an anti-reflection layer. The method comprises displacing some of the ions present in the diamond lattice structure at said areas with preselected ions, such as of C, Si, Fe, Ni, Ti or Au, by ion implantation means to produce desired optical properties, such as for lens coatings. The ion-implanted diamond body preferably is subjected to high temperature post-annealing.
