Abstract
Se propone un dispositivo (110) para determinar por lo menos una propiedad optica de una muestra (112). El dispositivo (110) comprende una fuente de luz de excitacion modulable (114; 410) para aplicar luz de excitacion (122) a la muestra (112). Y el dispositivo (110) comprende ademas un detector (128, 130; 312) para detectar la luz de deteccion (132, 136; 314) que emerge de la muestra (112). La fuente de luz de excitacion (114; 410) comprende un arreglo de diodos emisores de luz (114) que se configura por lo menos parcialmente como un arreglo de diodos emisores de luz monolitico (114). El arreglo de diodos emisores de luz monolitico (114) comprende por lo menos tres diodos emisores de luz (426) cada uno tiene un diferente espectro de emision.
