Abstract

ES UN DETECTOR OPTICO (5) DE EQUIPOS PARA MEDIR UNA SUSTANCIA EN UN LIQUIDO, HEMOGLOBINA EN SANGRE ENTERA POR EJEMPLO, PRESENTE EN UN RECEPTACULO TRANSPARENTE (6), COMPRENDE UN CUERPO (7, 8) QUE CONTIENE UN ASIENTO (11, 11'', 11") PARA EL RECEPTACULO (6), UNA FUENTE (22) DE RADIACION LUMINICA Y UN SENSOR OPTICO (27) ALINEADOS TRANSVERSALMENTE CON RESPECTO AL ASIENTO. LAS SUPERFICIES DEL ASIENTO (11, 11'', 11") SON REFLECTORAS. GRACIAS A LAS SUPERFICIES REFLECTORAS DEL ASIENTO (11, 11'', 11"), EL INDESEABLE EFECTO DE DISPERSION DE LA LUZ EN EL LIQUIDO SE REDUCE CONSIDERABLEMENTE Y EL DETECTOR (5) ES CAPAZ DE ENTREGAR UNA SEÑAL QUE POSIBILITA UNA DETERMINACION PRECISA DE LA CONCENTRACION DE SUSTANCIA A MEDIR.
