EQUIPEMENT ET PROCEDE DE FABRICATION DE COMPOSANTS OPTIQUES

摘要

The invention concerns a method and equipment for making optical components by irradiating a dielectric substrate (8) coated with a conductive layer (10) by vapour deposition, the irradiation being carried out by means of a beam of deflected electrons for deflector coils (4 to 6) to form a structured modification of refractive index. The invention is characterised in that the dielectric substrate is formed with doped silica.
