Abstract

Patente de Invenção: <B>"DISPOSITIVO PARA A MEDIçãO DA FLUORESCêNCIA EXCITADA POR LUZ, E A SUA UTILIZAçãO"<D>. A invenção refere-se a um dispositivo para medir a fluorescência excitada pela luz em pelo menos uma camada que contém um material fluorescente, e a sua utilização para medir materiais fluidos os quais efetuam a têmpera de fluorescência em pelo menos uma das camadas fluorescentes. Neste caso, o objetivo é de alcançar o objetivo de tornar disponível um dispositivo o qual pode ser de construção miniaturizada a ser adaptado flexivelmente a diferentes aplicações, e com a ajuda do qual é possível conseguir uma precisão de medição satisfatória. De modo a resolver este problema, a luz de pelo menos uma fonte de luz é direcionada para sobre pelo menos uma camada a qual é aplicada a um suporte e contém um material fluorescente. Para o propósito da fluorescência de excitação pelo menos um primeiro condutor ótico é direcionado para sobre a camada, e a luz fluorescente é direcionada por pelo menos um segundo condutor ótico para um detector para determinar a intensidade da luz fluorescente. Então as faces de extremidade dos vários condutores óticos para a luz fluorescente são dispostas, levando em conta as aberturas numéricas de todos os condutores óticos e/ou com referência a pelo menos uma camada que contém um material fluorescente, de tal modo que é possível atingir uma determinação de local da intensidade de fluorescência mensurável, e a(s) fonte(s) de luz, os condutores óticos e o(s) detector(es) são mantidos dentro de um cabeçote de medição.
