Abstract

Un fluorómetro que mide la fluorescencia de una muestra incluye una fuente de excitación para emitir la radiación electromagnética a lo largo de una primera vía de haz de rayos de luz para inducir la fluorescencia en la muestra. Un filtro de excitación transmite la radiación electromagnética de la fuente de excitación hacia la muestra. Un portador de filtro de excitación soporta el filtro de excitación y define una apertura para el pasaje de la radiación electromagnética de la fuente de excitación. La apertura es posicionada, en forma asimétrica, con relación a la primera vía de haz de rayos de luz, de manera que la apertura permita que una porción asimétrica de la radiación electromagnética en la primera vía de haz de rayos de luz pase hacia la muestra y que el portador de filtro de excitación bloquee el pasaje de una correspondiente porción asimétrica de la radiación electromagnética en la primera vía de haz de rayos de luz. El pasaje bloqueado de la correspondiente porción asimétrica de la radiación electromagnética en la primera vía de haz de rayos de luz reduce la cantidad de la radiación electromagnética orientada, en forma directa, del módulo de emisor al módulo de detector.
