Abstract

LENTES OFTALMICAS DE CRISTAL FOTOCROMICO CON UNA COMPOSICION DEL CRISTAL BASE R{SUB,2}O-AL{SUB,2}O{SUB,3}-B{SUB,2}O{SUB,3}SIO{SUB,3} Y UN METODO DE PRODUCIR LAS LENTES. LAS LENTES CONTIENEN CRISTALES DE HALURO CUPROSO PRECIPITADOS ALARGADOS Y ORIENTADOS, POR LO TANTO LAS LENTES SON CAPACES DE POLARIZAR LA LUZ CUANDO LA LENTE SE ENCUENTRA EN UN ESTADO OSCURECIDO. SI AL MENOS UNA PORCION DE LOS CRISTALES EN AL MENOS UNA CAPA SUPERFICIAL DE LA LENTE ESTA REDUCIDA A METAL CUPROSO, LAS LENTES MUESTRAN UN COMPORTAMIENTO DICROICO PERMANENTE. LAS LENTES PROPORCIONAN UNA POLARIZACION EFECTIVA DE LA RADIACION A TRAVES DE TODA LA REGION DE LONGITUD DE ONDA VISIBLE DEL ESPECTRO, TIENE UN CAMPO VISUAL ESPECTRAL AGUDO PARA LA RADIACION, POR DEBAJO DE UNA LONGITUD DE ONDA DE 400 NM, POR LO TANTO ELIMINA LA TRANSMISION RAYOS UV, Y TIENE UN FACTOR DE TRANSMISION NO SUPERIOR AL 40% EN LA CONDICION OSCURECIDA.
