Abstract

LA PRESENTE INVENCION SE REFIERE A UN DISPOSITIVO QUE PERMITE LA MEDICION DE LA INTENSIDAD DE LA LUZ DIFUNDIDA POR PELICULAS DELGADAS DE MEDIOS COLOIDALES. ESTA MAS PARTICULARMENTE DESTINADA A LA GRANULOMETRIA SUBMICRONICA POR CORRELACION DE FOTONES Y COMPRENDE UN DISPOSITIVO PARA MEDIR LA INTENSIDAD DE LA LUZ DIFUNDIDA POR PELICULAS DELGADAS (16) DE MEDIOS COLOIDALES QUE COMPRENDEN: UN SISTEMA OPTICO (4) CONVERGENTE QUE ENFOCA DICHA FUENTE SOBRE DICHA PELICULA DELGADA A ANALIZAR; OSENSIBLE (5; 5''; 5"; R"'') QUE REACCIONA A LA LUZ DIFUNDIDA O RETRODIFUNDIDA POR LA PELICULA DELGADA; RATAMIENTO (ELECTRONICO) DE LA SEÑAL OBTENIDA DEL (O DE LOS) FOTODETECTOR(ES) (5). SEGUN LA INVENCION, EL SISTEMA OPTICO COMPRENDE UN ELEMENTO DIOPTRICO (9) COLOCADO SOBRE EL TRAYECTO DE DICHO HAZ LUMINOSA Y UNA DE CUYAS CARAS (12) CONSTITUYE UNA PRIMERA PARED QUE DELIMITA DICHA PELICULA DELGADA, LA SEGUNDA PARED QUE DELIMITA LA PELICULA DELGADA EN SU ESPESOR ESTA CONSTITUIDA POR LA CARA INFERIOR DE UN MEDIO (20)CAPAZ DE ABSORBER TODO O PARTE DE LA INTENSIDAD TRANSMITIDA POR LA PELICULA DELGADA; EL DISPOSITIVO SEGUN LA INVENCION COMPRENDE ADEMAS UN MEDIOS (14) DESTINADO A POSICIONAR DICHO MEDIO (20) ENFRENTE DE LA CARA (12) DE ELEMENTO DIOPTRICO (9) ES DECIR DESTINADO A CONTROLAR EL ESPESOR DE LA PELICULA A ANALIZAR CON EL FIN DE ALCANZAR LOS PUNTOS DE FUNCIONAMIENTO APROPIADOS.
