Abstract

"SISTEMAS E MéTODOS PARA AUMENTAR A FAIXA ESPECTRAL DE UM ESPECTROFOTÈMETRO DE LED". A presente invenção refere-se a um dispositivo de espectrofotómetro de LED para determinar um aspecto da cor de um objeto que pode incluir: um espectrofotómetro visível que compreende uma pluralidade de diodos de emissão de luz que emitem luz no espectro visível por sobre o objeto; pelo menos um detector para detectar a dita luz após ser direcionada por sobre o objeto e para gerar uma saída; e um conjunto de diodo de emissão de luz UV que emite luz no espectro quase ultravioleta e combina com pelo menos um detector para gerar uma saída. O dispositivo pode ainda incluir um processador que combina as saídas do pelo menos um detector do espectrofotómetro visível e o pelo menos um detector em comunicação com o conjunto de diodo de emissão de luz UV.
