Abstract

APARELHO E MéTODO PARA MEDIR AS PROPRIEDADES ESPECTRAIS DE UM FLUIDO. A presente invenção refere-se a um aparelho e método para medir as propriedades espectrais de uma tinta, corante, esmalte ou outro fluido opaco, tanto em transmissão quanto em reflexão, em que um amplificador de bloqueio (5) é utilizado para aumentar substancialmente a razão de sinal-para-ruído de componentes transmitidos de radiação eletromagnética que passa pelo fluido, possibilitando assim que sejam feitas medições de transmitância da ordem de 0,0001% da radiação eletromagnética incidente.
