Abstract

UN NUEVO METODO DE OBTENCION DE SUPERFICIES OPTICAS PULIDAS EN VIDRIOS CONVENCIONALES UTILIZADOS EN LA INDUSTRIA OPTICA. SE TRATA, FUNDAMENTALMENTE, DE UN TRATAMIENTO TERMICO SUPERFICIAL REALIZADO MEDIANTE LA APLICACION CONTROLADA DE UN HAZ DE UN LASER DE C02 SOBRE LA SUPERFICIE DE LA MUESTRA A PULIR. LA FUERTE ABSORCION POR PARTE DEL MATERIAL DE LA RADIACION DE LONGITUD DE ONDA 10.6 MICRAS PROCEDENTE DEL LASER PROVOCA EL REBLANDECIMIENTO DE UNA FINA CAPA DE MATERIAL, LA CUAL FLUYE, BAJO LA ACCION DE LA TENSION SUPERFICIAL, DISMINUYENDO SU RUGOSIDAD. EL PROCESO SE COMPLETA CON UNA ETAPA FINAL DE ENFRIAMIENTO CONTROLADO Y RESOLIDIFICACION DE LA MUESTRA. PUEDE APLICARSE INDISTINTAMENTE A SUPERFICIES DE CUALQUIER TOPOGRAFIA CON RUGOSIDADES INICIALES DEL ORDEN DE 1-10 MICRAS, OBTENIENDOSE DESPUES DEL PROCESO UNA SUPERFICIE CON UNA RUGOSIDAD MAXIMA INFERIOR A 30 NM.A NEW METHOD OF OBTAINING POLISHED OPTICAL SURFACES IN CONVENTIONAL GLASSES USED IN THE OPTICAL INDUSTRY. IT IS, FUNDAMENTALLY, A SURFACE HEAT TREATMENT CARRIED OUT THROUGH THE CONTROLLED APPLICATION OF A BEAM OF A C02 LASER ON THE SURFACE OF THE SAMPLE TO BE POLISHED. THE STRONG ABSORPTION BY THE 10.6 MICRON WAVE LENGTH MATERIAL FROM LASER CAUSES THE SOFTENING OF A FINE LAYER OF MATERIAL, WHICH FLOWS, UNDER THE ACTION OF SURFACE TENSION, DECREASING ITS ROUGHNESS. THE PROCESS IS COMPLETED WITH A FINAL STAGE OF CONTROLLED COOLING AND RESOLIDIFICATION OF THE SAMPLE. MAY BE APPLIED INDISTINCATELY TO SURFACES OF ANY TOPOGRAPHY WITH INITIAL RUGOSITIES OF THE ORDER OF 1-10 MICRONS, OBTAINING AFTER THE PROCESS A SURFACE WITH A MAXIMUM RUGOSITY LESS THAN 30 NM.
