Abstract
LA PRESENTE INVENCION SE REFIERE A UN APARATO PARA ESCRIBIR EN Y/O LEER SOPORTES OPTICOS DE REGISTRO (AT) CON DIFERENTES ESTRUCTURAS, EL CUAL TRABAJA CON UNA UNICA LENTE DE OBJETIVO (OL). PARA ADAPTAR LA APERTURA AL TIPO CORRESPONDIENTE DE SOPORTE OPTICO DE REGISTRO (AT) UTILIZADO SE UTILIZA, CONFORME A LA INVENCION, UN DIAFRAGMA DE DIAMETRO VARIABLE, QUE ES EN ESPECIAL UN FILTRO DE POLARIZACION DISPUESTO EN LA TRAYECTORIA OPTICA. PUEDE REALIZARSE UNA CORRECCION DEL FRENTE DE ONDAS MEDIANTE UNA LENTE DIVERGENTE (SL) QUE PUEDE INSERTARSE ADICIONALMENTE EN TRAYECTORIA DEL HAZ. EL DIAFRAGMA FORMADO POR EL FILTRO DE POLARIZACION (PF) ESTA ACOPLADO A LA LENTE DE OBJETIVO (OL). EL CAMPO DE APLICACION ES EN ESPECIAL EL DE LOS APARATOS PARA LEER Y/O ESCRIBIR EN SOPORTES OPTICOS DE REGISTRO (AT) CON DIFERENTES ESTRUCTURAS, COMO POR EJEMPLO CD Y DVD.
