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.
